WASHINGTON (Reuters) - People will discover the consequences of US President Donald H. Trump's sudden threat to impose an additional 10 percent surcharge on consumer goods imported from China worth $ 300 billion, the Washington Post reported on Wednesday.

The newspaper added that Trump either intends to become the tariff in force on the first of next month, or it may be canceled in response to some of the actual concessions or expected from China.

Trump has chirped on Twitter, saying that China seems to be ostracizing its pledge to buy US agricultural products, and warned that Beijing, if stalled in negotiations in the hope of ending his term and not being re-elected in November 2020, .

China said it was illogical for Washington to exercise maximum pressure at this time.

Observers believe that the trade war between America and China is the most important obstacle facing the global economy, amid fears of an unexpected decline.

The newspaper stressed that what is already clear is that the United States, China and the world are facing a few weeks of uncertainty surrounding the largest bilateral trade relationship at the global level.

This uncertainty, and the uncertainty of the second largest relationship in the world between the United States and Canada, were also seen as confirming that Trump's policies had become one of the greatest sources of instability for the already fragile global economy.

She stressed that US Federal Reserve Chairman Jerome Powell last Wednesday referred to "trade tensions", although he did not blame President Trump.

The newspaper called on Trump to stop continuing the harassment of the Federal Reserve, before it really hurt the world's most important monetary policy maker.
