China seeks to "outlast" an escalating trade war with the United States and keep pressure on U.S. allies to "hedge," a former US diplomat said, as President Donald Trump's imposition of new tariffs and Beijing's retaliation have sharply raised tensions between the two superpowers.

There is no winner in a tariff war, and going against the world will only result in self-isolation, Chinese President Xi Jinping said when meeting with Spanish Prime Minister Pedro Sanchez here on Friday.

This came a day after US President Donald Trump announced a total of 145 per cent duty on Chinese goods.
