Against the yen, the dollar was a shade lower at 110.685 yen . It had brushed a five-week low of 110.285 yen per dollar during the previous session.

Late on Monday, U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin said China had moved away from commitments made over the course of trade negotiations.
Lighthizer said his office would probably put out a notice on Tuesday about a proposed increase in tariffs on $200 billion worth of Chinese goods to 25 percent from 10 percent.
Futures for the S&P 500 fell following the remarks. U.S. 10-year Treasury bond yields hit their lowest since May 1.
