Admittedly, China and the US have managed to maintain extensive cooperation on various bilateral, regional and international issues thanks to frequent high-level dialogues, which included the 7th US-China Strategic and Economic Dialogue in June. But like some traditional major powers and emerging ones in the past, they face the "Thucydides trap" (in which the differences between an existing power and a rising one leads to war), which they have to avoid.

China replaced Japan as the world's second-largest economy in 2010. A year later, it overtook the US to become the world's largest manufacturer. On the other hand, diplomatic tensions have been rising as Washington pushes ahead with its "pivot to Asia" strategy to contain China's rise, dragging both sides into deeper trouble with regard to the East and South China sea issues. Also, their disagreements on cybersecurity, human rights and the end of the super-national treatment China extended to foreign investors have further complicated the China-US relationship, in which cooperation and competition co-exist, with the latter apparently on the rise.

Another worrying factor for China is the pessimism shown by China watchers, some of whom say the China-US "honeymoon" is coming to an end. Such remarks highlight the need for both governments to take measures to control and manage their differences, old and new, and this is exactly what Xi aims to do during his US visit. He will meet American citizens from all walks of life, as well as business elites and members of think tanks, and his meeting with Obama could see the two leaders having a candid conversation on major issues facing the two countries.

On behalf of the Chinese government, Xi is expected to float and expound a set of new ideas on optimizing the global order while participating in the General Debate of the UN General Assembly in New York. In all likelihood, his visit will end with new agreements and concrete deals on bilateral cooperation, convince Washington of Beijing's adherence to peaceful development, and create an objective image of China in US citizens' eyes.
