Will US and China be able to lower risks before the new president takes office?
Sullivan’s trip, the first by a US national security adviser in eight years, may lay the groundwork for a meeting between Presidents Xi Jinping and Joe Biden, and the two leaders have already agreed to talk by phone in the coming weeks.
Any meeting – which could take place at the Asia-Pacific Economic Cooperation (Apec) or Group of 20 summits – would take place after the US presidential election in November. Beijing is likely to be extremely cautious in the run-up to the vote, especially given the possibility of a Donald Trump victory.
Observers also warned that even if a face-to-face meeting, or a trip to China by Biden, provided the opportunity to clarify their positions before the new president took over, it was not certain that it could make a clear difference to the relationship between the two countries.
Li Cheng, a professor of political science at the University of Hong Kong, said both Xi and Biden were keen to “make sure US-China relations are stabilised at this critical moment. They do not want to change the direction.”
