President Donald Trump and Chinese President Xi Jinping are expected to speak this week, a senior White House official told CNBC.

President Donald Trump and Chinese President Xi Jinping are ‘likely’ to speak soon, according to the White House, amid tensions rise over the US President's accusations that China violated a 90-day tariff rollback deal.

This comes as the European Union and Canada promise retaliatory tariffs if the president follows through on a threat made late last week.
