The dynamics of Sino-US relations after the election has become an increasingly complex and interesting topic to pay attention to. The elections taking place in both countries have had a significant impact on foreign policy and economic cooperation. Post-election in the United States, changes in leadership often influence diplomatic positions and strategies taken toward China. A different party’s victory in an election can lead to drastic policy shifts. If a party that is more confrontational towards China wins the election, there will certainly be an increase in tensions. On the other hand, if a party that values dialogue and cooperation wins seats, steps to ease tensions and strengthen diplomatic ties are likely. Post-election, one of the main indicators in Sino-US relations is trade. China and America are the two largest economies in the world, so new trade policies will greatly affect the global economy. Tariff policies, market access and trade agreements are important components that must be handled carefully. Approval of the new agreement could also affect domestic industries in both countries. On the security side, issues such as Taiwan and the South China Sea are still hot spots. Tensions in the region could increase or even subside depending on the policies adopted by new leaders in the US. If the US supports Taiwan more aggressively, this has the potential to trigger a strong reaction from China, conversely, if action is taken to maintain stability, then bilateral relations have the potential to improve. Changes in the technological arena are also crucial in the Sino-US dynamics. Policies related to technological innovation and intellectual property protection will be an important focus. China has ambitions to become a global leader in high technology, so tensions over data theft and industrial espionage are expected to continue. Environmental issues are also starting to become a concern in this relationship. China and the US, as the two largest emitters of greenhouse gases, need closer cooperation to overcome the climate crisis. Agreements in the field of renewable energy and pollution management could be a positive step to increase cooperation. Social media and the information space are also very influential after the election. Narratives appearing in the media can shape public opinion, strengthening or weakening relationships. In this digital age, propaganda and misinformation on both sides can exacerbate existing tensions. Therefore, an in-depth analysis of the post-election dynamics of Sino-US relations is crucial to understanding the future direction of the two countries. The ability to adapt and carry out diplomacy wisely will be the key to achieving regional and global stability and prosperity. As the situation develops, these two countries will continue to formulate policies that can prevent conflict while encouraging cooperation in various fields.
