Stock Markets Tumble After Trump Threatens to Dramatically Increase China Tariffs from 10% to 25%…

Global financial markets have been sent into a tailspin after Donald Trump risked jeopardising delicate trade talks with China by unexpectedly saying he would raise tariffs further on Chinese goods this week.

The huge drop in Chinese shares follows a three-day national holiday and came despite a move on Monday by China’s central bank to cut reserve requirements for smaller banks to help boost lending to small and private firms. Expect a busy currency market on Tuesday Morning…
