The US Trade Representative's Office issued a notice of postponing a 200-billion-dollar increase in tariffs on Chinese imports scheduled for early this month at a time when Washington asked Beijing to abolish customs duties on agricultural products.

A spokeswoman for the Office of Trade Representative Robert Laitheiser said the notice would be published in the Federal Register on Tuesday.

She added that the notification confirms that it is no longer appropriate to increase fees from 10% to 25% due to progress in negotiations between the two countries since last December.

The rate of surcharges, which came into force last September, will remain at 10% until further notice, the notice said.

In a related context, US President Donald Trump asked China to abolish tariffs on agricultural products imported from the United States.

Trump wrote in a tweet on Twitter that he had asked China to immediately abolish all duties on these products, including beef, pork and others.

The US president attributed the reason for the demand for good progress in the ongoing negotiations between the two countries.

White House adviser Larry Kudlo said he believed last weekend that the United States and China were moving towards a trade deal that he described as historic.
