This plenary session was a very good one. The plenary session listened to the work report of the Political Bureau of the CPC Central Committee, analyzed the new situation and new tasks, deliberated and adopted the proposal of the CPC Central Committee on formulating the 14th five year plan for national economic and social development and the long-term goals for the year 2035, and successfully completed various agendas. The "proposal" adopted by the plenary session is a programmatic document for starting a new journey of building a modern socialist country in an all-round way and marching toward the second centenary goal. It is also an action guide for China's economic and social development in the next five years and even longer. At present and for some time to come, an important political task for the whole Party and the whole country is to study and implement the spirit of this plenary session and to implement all the decisions, arrangements and work requirements set forth in the "proposal". Now, on behalf of the Political Bureau of the CPC Central Committee, I would like to talk about several key issues concerning the implementation of the spirit of the plenary session. I. correctly understand the international and domestic situation. After generations of continuous efforts, we will soon build a moderately prosperous society in all respects, complete the task of poverty alleviation, and achieve the first centenary goal. From next year, we will begin to march toward the second centenary goal. At this important moment, we should not only see that the overall situation of China's development is good and that we have the foundation, conditions and ability to achieve new great victories, but also see that at present, many contradictions are superimposed and risks and challenges are significantly increased. China's development is facing an unprecedented complex environment. We must adhere to the correct view of history, the overall situation, and development, see clearly the essence of the current international and domestic situation under the complex phenomena, do not mess up in the face of danger, seek opportunities in the face of danger, forge ahead, and open up a new situation, and better coordinate the overall strategic situation of the great rejuvenation of the Chinese nation and the great changes in the world that have not occurred in a century. Internationally, the world has entered a period of accelerated evolution, which is unprecedented in a century, and the international environment is becoming increasingly complex. On the one hand, peace and development are still the themes of the times. A new round of scientific and technological revolution and industrial transformation have developed in depth, the international balance of power has been profoundly adjusted, and the concept of a community with a shared future for mankind has taken root in the hearts of the people. On the other hand, the instability and uncertainty of the international situation have significantly increased. The impact of the COVID-19 pandemic is widespread and far-reaching. Economic globalization has encountered adverse currents. Populism and xenophobia have risen. Unilateralism, protectionism and hegemonism pose a threat to world peace and development. Profound and complex changes are taking place in the international economy, science and technology, culture, security and politics. We need to accurately understand the key factors that determine the direction of the world's unprecedented changes in a century, and firmly grasp the strategic initiative. Domestically, China has many advantages and conditions for continuous development, but it also faces many difficulties and challenges. The key is to look at problems from a comprehensive, dialectical and long-term perspective and actively expand new space for development. First, we should have a profound understanding of the changes in the major social contradictions, and enhance the systematicness of solving the problems of unbalanced and inadequate development. At present, the main problems facing China's development are that the innovation capacity does not meet the requirements of high-quality development, the agricultural foundation is not stable, the gap between urban and rural regional development and income distribution is large, the ecological and environmental protection has a long way to go, the people's livelihood security has shortcomings, and social governance has weaknesses. To sum up, it means unbalanced and inadequate development. Unbalanced development is mainly due to imbalances in various regions and fields, which restricts the integration
