Global issues are acute and complex.The game between major powers is becoming increasingly fierce,geopolitical competition is intensifying,and factors of instability,uncertainty,and insecurity in the international situation are becoming increasingly prominent.How can China's diplomacy continue to innovate and make breakthroughs to create a favorable external environment for Chinese-style modernization?How to inject more certainty into an uncertain world?To this end,the editorial department and the School of Political Science and International Relations of Tongji University jointly invited scholars to discuss the relevant issues.Professor Tang Yongsheng pointed out that in the new era,China's diplomacy should establish positive and feasible strategic goals,adhere to the basic direction of peaceful development,and actively participate in the construction of multilateral mechanisms.Researcher Li Kaisheng believed that Chinese-style modernization needs an overall open economic environment,a healthy competitive political environment and a relatively peaceful security environment.He proposed suggestions such as reshaping a multipolar pattern through stabilizing major country relations,and supporting global mechanisms to play a greater role.Professor Men Honghua emphasized that as the strategic competition between the United States and China intensifies,the trend of"pan security"is becoming more prominent in the policies of the United States,Europe,and Japan towards China."Pan security"seriously affects the normal operation of the global political,economic,and security system,becoming an important factor that disrupts and undermines international cooperation and global governance.China needs to respond strategically from the perspectives of ideology,policies,and systems.Professor Hu Zongshan believed that on the premise of fully considering the competitive strategy of the United States towards China,China should adhere to the main strategies of independence and self-reliance,compound checks and balances.Researcher Sun Degang proposed that China needs to leverage its geographical advantages,taking the"Global East"as a new breakthrough and upgrading its peripheral diplomacy to"Greater Peripheral Diplomacy",which integrates the diplomacy of major powers,neighboring countries and developing countries.Professor Li Shu pointed out that the politicization,weaponization,nationalization,and ideology of technological issues pose many challenges to China's technological innovation and development.It is particularly urgent for China to promote the construction of a new type of international relations and respond to global changes through science and technology diplomacy.
