Opening up brings progress, while closing is bound to lag behind. Opening up will not be smooth, but accompanied by opportunities and challenges, moving forward in twists and turns. "Can we make use of the opportunities of opening to the outside world and not be corrupted or eaten?" in January 2016, at the provincial and ministerial level leading cadres' study and implementation of the the fifth Plenary Session of the 18th CPC Central Committee Seminar on the spirit of the party, general secretary Xi Jinping raised a question that many people were concerned about. In Xi Jinping's view, as long as we actively comply with the trend of world development, we can not only develop ourselves, but also lead the world's development trend. one Since modern times, the industrial revolution has brought great changes to the productivity of the external world. However, the decadent rulers of the Qing Dynasty were immersed in the dream of "heaven on the country", closed the country and eventually fell behind and were beaten, and the Chinese nation suffered unprecedented disaster. After the founding of new China, facing the blockade of the western world, we explored the road of socialist construction in a relatively closed environment. After the Third Plenary Session of the 11th CPC Central Committee, the spring tide of reform and opening up surged and the modernization drive moved forward with great strides. Today's world is undergoing great changes that have not been seen in a century. The global economy is in a downward period, and the "cake" is not easy to grow or even become smaller. The contradictions between growth and distribution, capital and labor, efficiency and equity have intensified, and both developed and developing countries feel the pressure and impact. The spread of novel coronavirus pneumonia is a serious threat to global public health. Mankind is experiencing multiple crises rarely seen in history. The situation is complex and severe, and the challenges are unprecedented. Whether it is open, why it is open and how it is open are a "must answer" for policymakers in various countries. "The problem now is not whether to open to the outside world, but how to improve the quality of opening to the outside world and the internal and external linkage of development." "economic globalization has indeed brought new problems, but we can't beat it to death. Instead, we should adapt to and guide economic globalization, eliminate the negative impact of economic globalization and make it better benefit every country and nation." "We need to open up walls instead of building walls. We must open up rather than isolate them. We must integrate and not decouple". "The door of China's opening will not be closed, it will only grow bigger and bigger". On many occasions, Xi Jinping gave a clear answer. In October 2015, the Fifth Plenary Session of the 18th CPC Central Committee first put forward the new development concept of innovation, coordination, green, openness and sharing, and opening up has become an important part. In the nineteen major reports, Xi Jinping has made a blueprint for opening up to the outside world: "forming an open pattern of internal and external linkage and two-way exchanges between East and west", "actively participating in and promoting the process of economic globalization, developing a higher level open economy, and continuously strengthening China's economic strength and comprehensive national strength". Novel coronavirus pneumonia pull together in times of trouble. The world economic recovery is rough. People in all countries need to work together in a more difficult time and make a difficult time. Yi Qu, a public security walker, is a very difficult way to solve this problem. On the opening ceremony of the fourth China Fair held in November 4th this year, Xi Jinping mentioned the 3 "change": China's determination to expand high-level openness will not change, and the determination to share development opportunities with the world will not change. The determination to push economic globalization towards a more open, inclusive, inclusive, balanced and win-win development will not change. "China is willing to work with other countries to build an open world economy and let the open spring breeze warm the world!" China opens its arms to the world. two "As soon as the train rings, there will be ten thousand taels of gold." a China Europe train loaded with containers runs fast on the Eurasian continent. The latest data show that China Europe trains have operated more than 40000 in total, opened 73 operation lines, reached more than 170 cities in 23 countries in Europe, and transported more than 50000 kinds of goods One belt, one road, is the important achievement of the "one belt and one way" construction. It is also one of the links of China's opening up to the outside world in the new era. One belt, one road, and 141 countries have signed a cooperation agreement with the Chinese side in the past 8 years. All parties have actively promoted policy communication, facility connectivity, smooth trade, financing and people to people communication, launched a large number of practical cooperation projects for the benefit of the people, and built an all-round and composite connectivity partnership. "One belt, one road" is a sunny road for us to go forward hand in hand, not a private path for one side. All interested countries can join in, participate in, work together and benefit together. "Xi Jinping invites the world. Opening up is a distinctive symbol of contemporary China. Set up 21 pilot free trade zones nationwide to replicate and promote a large number of opening-up experience; Set up the world's first national exhibition with import as the theme - China International Fair; Set up a Consumer Fair in Hainan; Promote the rapid development and growth of the service trade fair held in Beijing; Lower the threshold of foreign capital access, and the "negative list" is getting shorter and shorter; Protect intellectual property rights and promote the implementation of the foreign investment law of the people's Republic of China and the regulations on optimizing the business environment; Formal accession to the regional comprehensive economic partnership agreement (RCEP); China has actively applied to join the comprehensive and progressive trans Pacific Partnership Agreement (cptpp)... China's pace of opening up has never stopped. This year marks the 20th anniversary of China's accession to the world trade organization. Over the past 20 years, China has fully fulfilled its WTO accession commitments, and the total tariff level has decreased from 15.3% to 7.4%, lower than the WTO accession commitment of 9.8%; China's central government cleaned up more than 2300 laws and regulations and local governments cleaned up more than 190000, which stimulated the vitality of the market and society. Over the past 20 years, China's continuous expansion of opening up has activated the surging spring tide of China's development and a pool of spring water of the world economy. More overseas market players choose to "overweight China" with practical actions. In 2020, China's actual use of foreign capital was 144.37 billion US dollars, about 14 times that of 1990. With a population of more than 1.4 billion and a middle-income group of more than 400 million, China imports about US $2.5 trillion in goods and services every year, and the market is very large. According to CNN, BlackRock, Goldman Sachs, Fidelity International and other well-known financial institutions have recently advised customers to continue to "buy China". "China has fulfilled its commitment to expand opening-up and improve the level of opening-up with practical actions," said fan Ruisi, President of Yizi Greater China, who has participated in the Expo for four consecutive years. three Expanding opening up is by no means tantamount to giving up independence. China should firmly hold the initiative of development in its own hands. The Fourth Plenary Session of the 19th CPC Central Committee pointed out the direction in the face of the new situation. "Accelerate the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other", the Fifth Plenary Session of the 19th CPC Central Committee made a comprehensive deployment. Xi Jinping pointed out that amidst the winds of change, we must make efforts to make the international circulation change without any efforts to make the big domestic cycle work smoothly. Today, China is the world's second largest economy, the largest industrial country, the largest trade in goods and the largest foreign exchange reserve country, with a GDP of more than 100 trillion yuan. In 2020, China's total import and export of goods reached US $46.26 billion. In the same year, China's foreign direct investment was US $153.71 billion, ranking first in the world for the first time. Not long ago, the United Nations Office for project services (UNOPS) issued a long-term procurement qualification bidding project for agricultural machinery. Zoomlion won the qualification of "long-term supplier", took a key step of "going global", and broke the long-term monopoly of foreign brands in this field. On the world economic stage, China's share is increasing and its influence is "leverage". Now, from high-speed trains and energy equipment to smart phones and household appliances, made in China, built in China and created in China, they not only serve the domestic market, but also are welcomed by the global market. The latest data show that in the first three quarters of this year, the import and export of national goods trade reached 28.33 trillion yuan, and the international market share of import, export and import increased. Among them, the export of high value-added products such as mobile phones, household appliances, automobiles and ships increased strongly. In October 2020, when inspecting the Guangdong Chaozhou Sanhuan (Group) Limited by Share Ltd, Xi Jinping said to the employees who had gathered around him - "History is always spiraling upward. In the past, our opening-up was' following ', but now our opening-up is to' lead ', which is a higher level of opening-up." (outlook new era)
