The Australian dollar gained 0.4 percent to $0.7157, reacting to Trump's latest posts on Twitter.

The offshore yuan strengthened 0.3 percent to 6.6806 yuan  against the dollar, its highest level since mid-July, also on the news he will not raise tariffs on $200 billion of Chinese imports to 25 percent from 10 percent.

The U.S. president also said he would plan a summit meeting with Chinese President Xi Jinping at his Mar-a-Lago estate in Florida to conclude an agreement, assuming the trade talks make additional progress.

Indeed, Trump's tweets came amid rising expectations that he would delay increasing higher tariffs before the March 1 deadline to avoid escalating the U.S.-China trade war.

The president said in a tweet that progress had been made on a host of divisive areas including intellectual property protection, technology transfers, agriculture, services and currency.
