Anything can happen in an escalating trade war between US and China. According to Goldman Sachs. US institutions currently hold some $250 billion or 26% of total Chinese ADRs while their Hong Kong stock holdings amount to $522 billion. Together with their holding of China A Shares, total exposure of some $800 billion. In the extreme scenario of financial separation between the two countries, US investors could potentially be forced to divest of their investment holdings in China equities.
