U.S. President Donald Trump on Friday offered a pessimistic view on reaching a trade deal with China, saying Beijing may not sign one before the November 2020 election in hopes a Democrat who will be easier to deal with, will win.

During a wide-ranging session with reporters in the Oval Office, Trump said China is using stalling tactics and he doubted a trade deal will be reached any time soon, with lead negotiators for the two countries to meet in Shanghai in the coming week.

Trump has been tough on Chinese trade practices throughout his presidency and has levied billions of dollars in tariffs on Chinese imports and threatened another $325 billion if no progress is reached.
