U.S. President Donald Trump said on Wednesday that a trade deal with Chinese President Xi Jinping was possible this weekend, but that he is prepared to impose U.S. tariffs on virtually all remaining Chinese imports if the two countries continue to disagree.

Trump, who departed for the G20 leaders summit in Osaka the same day, also raised the possibility that he may impose a lower, 10 percent duty on a $300 billion list of Chinese imports, instead of the currently proposed 25 percent rate.

Trump is expected to meet with Xi on Saturday, to hold a conversation that could revive stalled negotiations between the world's two biggest economies or launch a much deeper, costlier trade war that would drag down global growth and roil financial markets.
