China sells the most US assets in 4 years, dumping $21 billion of US stock and Treasury bonds

• Chinese investors sold $21.2 billion in US equities and Treasuries, the US Treasury said Wednesday.
• Chinese investors sold an all-time record $5.1 billion of US stocks that month.
• The onshore yuan had weakened against the dollar to its lowest point since November in August.

Chinese investors offloaded $21.2 billion of US assets in the month of August, the most in four years, according to US Department of the Treasury data cited by Bloomberg.

The dumping of US securities comes as the onshore yuan weakened in August to its lowest point since November, fueling speculation Beijing is looking for ways to prop up its currency.
