While a diffusing of tensions is good, this is more likely about Xi being dead or deposed. Still haven’t seen any public appearances or mentions of him by the Chinese.

Why now after not doing so since 2016? Could it be to coordinate all the Chinese sleeper cells that walked across the US border in the last 4 years to foment unrest before the election? https://www.zerohedge.com/geopolitical/series-us-china-cloak-dagger-summits-led-weeks-sullivan-trip-beijing
