The initiative of jointly building the "the Belt and Road" has gone through its first vigorous decade and is in its prime. From vision to reality, the "the Belt and Road" has become the most popular international public goods and the largest international cooperation platform in the world. The third "the Belt and Road" International Cooperation Summit Forum held in Beijing not long ago attracted representatives of 151 countries and 41 international organizations to attend the conference, with a total number of registered people exceeding 10000. This "10000 people event" also kicked off the next golden decade of the "the Belt and Road". Focusing on how the "the Belt and Road" cooperation will continue to develop in high quality, the reporter interviewed Zhai Dongsheng, director of the Belt and Road Construction Promotion Center of the National Development and Reform Commission. The spirit of the Silk Road is enduring and enduring Provide strong internal drive Over the past 10 years, the total import and export volume between China and co built countries has accumulated to 19.1 trillion US dollars, with an average annual growth rate of 6.4%. This growth rate is both higher than the overall growth rate of China's foreign trade during the same period and higher than the global trade growth rate during the same period. As of the end of 2022, Chinese enterprises have invested a total of 57.13 billion US dollars in the construction of overseas economic and trade cooperation zones in countries along the route, creating 421000 job opportunities for the local area and lifting nearly 40 million people out of poverty. "Over the past 10 years, the joint construction of the 'the Belt and Road' has recorded brilliant achievements, and has achieved positive results in improving the level of global all-round connectivity, releasing the potential of economic, trade and investment cooperation, expanding new space for international cooperation, improving the well-being of the people's livelihood of the country, and improving China's level of opening up." Zhai Dongsheng said. Looking back on his ten year journey, Zhai Dongsheng has many feelings. "In recent years, great changes have taken place in the international and domestic situation. Some countries led by the United States have begun to pursue unilateralism and trade protectionism, which has caused fluctuations in the international economic order and intensified Sino US trade frictions." Zhai Dongsheng said that while facing many challenges, the "the Belt and Road" has insisted on win-win cooperation, which has received universal international response. Why is the joint construction of the "the Belt and Road" initiative proposed and spearheaded by China feasible? Zhai Dongsheng believes that the most important thing is to have clear guidance from scientific theories. The joint construction of the "the Belt and Road" has the spirit of the Silk Road with peace and cooperation, openness and inclusiveness, mutual learning and mutual benefit as the core, and the rich connotation of high-quality joint construction of the "the Belt and Road". As a symbol of communication and cooperation between the East and the West, the millennium old Silk Road profoundly demonstrates that as long as we adhere to unity and mutual trust, equality and mutual benefit, inclusiveness and mutual learning, and win-win cooperation, countries of different ethnicities, beliefs, and cultural backgrounds can fully share peace and common development. Jointly building the "the Belt and Road" will carry forward the spirit of the Silk Road in the new era, arouse people's good memories of the past times, and stimulate the enthusiasm of countries to achieve connectivity. "The Silk Road spirit, rooted in history, is in line with the trend of peace, development, cooperation and win-win in the current era, and runs through the ten years of 'the Belt and Road' cultivation, making it show great vitality and strong attraction," said Zhai Dongsheng. Mechanism and Capability Guarantee Overcoming "Growing Pains" "As a world project and a century project, the" the Belt and Road Initiative "has been built together for ten years. It is still in its' youth 'period, and naturally there are' growing pains'," Zhai Dongsheng said vividly. Zhai Dongsheng said that in earlier years, some Chinese enterprises had a rapid pace of "going global", but the level of internationalization did not keep up in a timely manner and lacked experience in international cooperative management. For example, familiarity with foreign laws and regulations, awareness of ecological and environmental protection in the business process, and reserve of comprehensive talents. "However, these 'growing pains' can not stop the joint construction of the" the Belt and Road "in any way." Zhai Dongsheng believes that the joint construction of the "the Belt and Road" has made full use of the combination of effective markets and promising governments to achieve a good mechanism guarantee. In addition to China's strong hard power support, it can be said that theoretical guarantee, mechanism guarantee and capacity building guarantee are the foundation and confidence of the "the Belt and Road". Zhai Dongsheng said that the three high-level forums and six thematic forums of this Summit Forum are China's adherence to the concept of openness, green and integrity of the "the Belt and Road", and firmly reaffirm China's attitude and determination to the world. By actively engaging in dialogue, all parties will surely further cooperate in areas such as the Open Silk Road, Green Silk Road, and Clean Silk Road. "The success of this summit forum shows that China is in the right direction to promote the joint construction of the the Belt and Road, that all countries have strong confidence in participating in the joint construction of the the Belt and Road, and that the high-quality development of the the Belt and Road has a bright future." Zhai Dongsheng believes that the summit forum, as a landmark event, means that the "the Belt and Road" will embark on a new journey of development. We need to guard the basic situation well More importantly, we need to continuously add new vitality The next decade of the "the Belt and Road" is beginning. How can we act? Zhai Dongsheng believes that in the future, we should not only consolidate the existing cooperation achievements, that is, adhere to the existing traditional and advantageous cooperation areas and friendly key cooperation areas under co construction, but also expand new areas, including green, health, digital, innovation, international poverty reduction cooperation, and other fields, making them new growth points for co construction. At the same time, we should continue to add new vitality and new impetus to the joint construction of the "the Belt and Road". Encourage and guide multinational corporations and international financial institutions, including Hong Kong and Macao enterprises, to actively participate in the co construction process, forming a diversified and internationalized construction and investment financing; Encourage qualified private enterprises to actively "go global" and explore areas and fields that support the development of private enterprises; Accelerate the cultivation of domestic high-end service industries, such as engineering design, consulting, and asset evaluation, and improve their international operational capabilities and levels, so that they can[

Recently, the state has again adjusted the export tax policy of the iron and steel industry, raised the export tariff of ferrochrome and high-purity pig iron, and cancelled the export tax rebate of 23 iron and steel products. This also means that the 169 tax lines that originally enjoyed export tax rebate in China will be cancelled and reduced to 0, and the export of domestic steel products will no longer enjoy the export tax rebate bonus. According to the analysis of some experts, the purpose of this adjustment is to reduce the export volume of primary products and related steel products and give priority to ensuring the supply in the domestic market. In the long run, the cancellation of export tax rebate bonus by Chinese iron and steel enterprises is more conducive to the development of the industry. The export of iron and steel enterprises will be affected On July 29, the Tariff Commission of the State Council announced that in order to promote the transformation, upgrading and high-quality development of the iron and steel industry, the export tariffs of ferrochromium and high-purity pig iron will be appropriately increased from August 1, 2021, and the export tax rates of 40% and 20% will be implemented respectively after adjustment. On July 29, the Ministry of Finance and the State Administration of Taxation announced that 23 export tax rebates for iron and steel products would be cancelled from August 1, 2021. Tariff adjustment will be first reflected in the export price of iron and steel products. According to the data of Lange Iron and Steel Research Center, taking hot rolled coil as an example, at the end of April, the export price of China's hot rolled coil was 921 US dollars / ton, 29 US dollars / ton lower than that of India and 69 US dollars / ton lower than that of CIS; On August 10, the export quotation of China's hot rolled coil was 929 US dollars / ton, 29 US dollars / ton higher than that of India and 19 US dollars / ton higher than that of CIS; The new export order index of iron and steel enterprises has continued to fall since May, only 30.8% in July. In an interview with Huaxia times, Wang Guoqing of Lange Iron and Steel Research Center said that for iron and steel export enterprises, the increase of export tariff on primary products and the cancellation of export tax rebate on related products will increase the export cost of relevant enterprises. Enterprises have to increase export quotation to offset the cost increase caused by tax rate adjustment, and the advantage of export price is gradually weakened, In the later stage, the export volume of steel will drop significantly. With the reduction of price advantage, tariff adjustment will undoubtedly have a significant impact on the export business of China's iron and steel enterprises. Cao Jianyong, chief analyst of plate and strip of Shanghai Steel Union steel division, told the Huaxia times that from the perspective of total volume control, the export volume of iron and steel enterprises will decline, which will have a great impact on the short-term interests of enterprises, but this is mainly for enterprises with large export volume of primary products, High end products and deep-processing products are not affected much. No longer enjoy export tax rebate bonus In addition to the impact on the export of iron and steel enterprises, the readjustment of iron and steel export tax policy is also of great significance to the whole industry. The export tax rebate policy adjustment is based on the announcement on canceling the export tax rebate of some iron and steel products (Announcement No. 16 of the Ministry of Finance and the State Administration of Taxation in 2021) published on April 28, 2021, and further cancels the export tax rebate of iron and steel products with 23 tax numbers retained after the previous policy adjustment. In this regard, according to the analysis of Ping An Securities, this also means that since August 1, the export tax rebate of 169 tax numbers of domestic steel products that originally enjoyed export tax rebate will be cancelled and reduced to 0, and the export of domestic steel products will no longer enjoy the export tax rebate bonus. However, after the cancellation of export tax rebates for some steel products in May, due to the fact that the overseas market price is significantly higher than that in China, the export willingness of enterprises is strong, and the steel export quotation also has obvious advantages, the steel export scale is still large. According to the data of the General Administration of customs, China exported 5.271 million tons and 6.458 million tons of steel respectively in May and June this year, with a year-on-year increase of 19.8% and 74.5% respectively, In the same period, steel imports hovered at a low level, showing a large-scale net export as a whole. "This is the second time in the year to adjust the relevant export tax rate and cancel the export tax rebate." According to Wang Guoqing's analysis, the purpose of this adjustment is to reduce the export volume of primary products and related steel products. The first task of the current development of the iron and steel industry is to ensure domestic supply and not leave pollution and carbon emissions at home. Export constraints will correspondingly reduce the demand for iron ore, which is conducive to the guarantee of China's raw material resources and the return of export resources to China, At the same time, it is also conducive to the rational return of iron ore price, ensure the reasonable profit of China's iron and steel industry, ensure the supply of domestic iron and steel market and maintain the stability of domestic market. In the long run, the cancellation of export tax rebate bonus by Chinese iron and steel enterprises is more conducive to the development of the industry. According to Cao Jianyong's analysis, at present, the export business of China's iron and steel industry is relatively extensive. Under the big goal of carbon neutralization and carbon peak, the iron and steel industry should give priority to ensuring the supply of the domestic market, reducing the export of primary products and encouraging import. For the iron and steel industry, it is necessary to reduce unnecessary primary product production, promote the transformation and upgrading of internal consumption, and finally achieve the purpose of optimizing the industry structure. The reduction of exports will bring some losses to enterprises, but in the long run, this is also the trend. China's iron and steel industry is facing new changes Under the goal of carbon peak and carbon neutralization, Ductile manhole cover, Cast Iron manhole cover, Ductile Iron Manhole cover, Also as Ductile Gratings, Cast Iron Gratings, Ductile Iron Gratings and steel enterprises have to face new emission reduction tasks in addition to making profits. Iron and steel enterprises need to make self-change. Carbon reduction and capacity reduction have become the main theme of the moment. For the current development situation of iron and steel enterprises, Cao Jianyong said that China's iron and steel industry is experiencing a change of times and a change from quantity to quality. Reducing energy consumption and improving the ecological environment in the iron and steel industry need to be jointly maintained by large carbon emission industries. It is imperative for the iron and steel industry to reduce the production of primary products and adjust the product structure. It is the general direction of the industry to ensure the stability of the domestic market and adjust the regional concentration of iron and steel, so as to achieve orderly development. At present, the export tax rebate of primary products in the iron and steel industry has been basically cancelled. In terms of export tax rebate, there is no content that can be adjusted. Is it possible to further raise tariffs in the future? According to Wang Guoqing's analysis, despite the gradual effect of China's export tax rebate cancellation policy, under the strong overseas demand for steel, the steel export still showed a significant growth year-on-year in July. With the development of domestic crude steel output reduction and the need to maintain supply and price stability, the tariff of previously cancelled export tax rebate products may be increased in the later stage to ensure the stability of domestic supply and market. For the future trend of the iron and steel industry, Lange Iron and Steel Research Center analyzes that the overall overseas steel market has shown signs of inflection point, the expansion of steel demand has slowed down, the gap between supply and demand in the market has narrowed, and the price action force is insufficient. In July, the growth of the North American market was significantly narrower than that in the early stage. The European market ended the rising trend of the past year and began to decline slightly. The Asian market continued to adjust the differentiation trend. With the adjustment of the overseas market and the rebound of the domestic market, the price advantage of China's steel export is gradually lost, and the export orders fall. At the same time, the cancellation scope of export tax rebate is expanded, and the inhibition on steel export will further appear. It is expected that the steel export will gradually fall in the second half of the year, and the export volume will be reduced compared with the first half of the year.

"It's a headache to encounter the manhole cover on the road when driving. If you roll it carelessly, the vehicle will bump at least, or damage the vehicle or even have a traffic accident. It's a good thing to replace these old well covers now! ". Urban construction is inseparable from various pipe networks and observation wells such as water supply and drainage. Due to the needs of construction and maintenance, many observation wells remain on the motorway. After these observation wells have been continuously rolled by vehicles for a long time, they will collapse, sink and damage to varying degrees, which will not only affect the city image, but also have potential traffic safety hazards. Because the well Manhole Cover is uneven with the road after sinking or tilting, whenever a vehicle passes through the well cover, it will make a "clang, clang" sound. Sometimes when the well cover is damaged and the driver has no time to avoid, the wheels will jam at the wellhead, damage the vehicle and even cause a traffic accident. China has replaced well Cast Iron manhole Cover set on motor and non motor lanes. Ductile Iron Manhole Cover cover is changed from the previous ordinary Ductile Manhole Cover to nodular cast iron well Manhole Cover. There are three clips on the well hoop to connect the well cover with the well hoop, and there is a rubber ring at the contact between the well cover and the well hoop, which can reduce the noise caused by metal collision. BMH cold mix and cold paving asphalt mixture composed of organic high molecular polymer is used for filling pavement. This material has good adhesion and can be paved and compacted on the construction site without affecting vehicle traffic for a long time due to construction. According to Lu biyou, an engineer of Changji Tingzhou Haotai road and Bridge Co., Ltd., which is under construction on site, this new well cover also has the advantages of "five prevention", that is, anti theft, anti settlement, anti collapse, anti displacement and anti noise, and can withstand the rolling of 100 tons of heavy trucks. Many cities have replaced all well covers on the eve of national day on October 1. After replacing the new well cover, it will not only increase the flatness of the motorway pavement, but also improve the traffic safety of urban roads. "
