Xi retaliated against the US instead of negotiating tariffs with Trump. He wouldn't come to the table like other nations did, so China isolated themselves from the world. Then they tried to gain allies in their fight against US trade tariffs. The EU and Australia don't want to be involved with China's fight.

Yesterday, Trump excluded smartphones, computers and other electronic devices from tariffs to give American businesses time to move production to the US in the next two years. I'm not sure how this will affect China trade talks but they probably don't like the idea of all those businesses leaving their country. Maybe its a wake-up call for Xi that he has to make a deal.
