In the event of a serious US Recession, China is exposed, IMO,
because the US accounts for 28% of China's total exports.

Most of those exports are of the Walmart cheap goods variety
and, like US consumer buying habits during the GFC, they will likely
be less impacted than the high priced imported goods from Europe
& Japan, IMO.

A serious US Recession could mean that China could pass out
the USA in GDP (USD) earlier than anticipated . China overtook
the USA in GDP (PPP) in 2015 which started the US panic
about China and motivated Trump to impose tariffs on Chinese
non essential imports to improve the US trade deficit with China
&, to a lesser extent, stymie China's economic growth.

All IMO.
