US-China relations, a cornerstone of global geopolitics, are at a juncture that could favor significant change as the political climate in the United States remains uncertain. Chinese political scientist Yan Xuetong posits that although the bilateral ties may become more tumultuous, the potential re-election of Donald Trump could paradoxically offer advantages to China in several ways.

One key aspect is Trump's administration tendency to upend conventional diplomatic strategies. This unpredictability, while initially destabilizing, may allow China to exploit gaps in US policy more effectively. During Trump's first term, some Chinese analysts observed a certain advantage as the Trump administration's focus on isolating itself from multilateral agreements created opportunities for China to increase its influence in global institutions and negotiations.

The internal dynamics of the US political landscape are anticipated to provide China with indirect benefits. The possible return of Trump's foreign policy approach, characterized by unilateral decisions and America-first rhetoric, might further strain US relations with traditional allies. This environment can potentially position China as a more stable and appealing partner on the international stage.

However, despite these potential benefits, Yan warns that the road ahead remains rocky. A potential second Trump term isn't without its challenges for China. Intensifying trade conflicts, technology restrictions, and heightened military tensions in the South China Sea and Taiwan Strait could escalate, requiring astute diplomatic and strategic maneuvering by China to maintain stability.

Moreover, China's own reforms will critically define how beneficial any political shift in the US might become. China's ability to adapt to external pressures through economic reforms and technological self-sufficiency is paramount. Its initiatives to reduce reliance on foreign technologies and boost domestic innovation will be essential in capitalizing on any strategic openings that may arise from US political upheavals.

In conclusion, while Trump's potential return to the presidency could indeed bring about advantages for China, these must be carefully measured against the backdrop of escalating tensions and the necessity for prudential reforms. The evolving US-China relationship, oscillating between conflict and opportunity, continues to significantly impact both nations and the wider global order. Although challenges remain, strategic adaptations on both sides could shape a new era of interaction in this complicated bilateral relationship.
