$10bn Trump-approved sale to Taipei triggers Beijing sanctions against firms such as Boeing and Northrop Grumman

China’s foreign ministry has hit US defence companies including Boeing with sanctions after Donald Trump approved a large package of arms sales to Taiwan.

The ministry said on Friday that the measures – against 10 individuals and 20 US firms including Boeing’s production hub at St Louis in Missouri – would freeze any assets the companies and individuals hold in China and bar domestic organisations and individuals from doing business with them.
