The optimism around a partial resolution to the festering trade dispute faded a bit after a U.S. administration official told Reuters that an interim agreement might not be completed in time for signing in Chile next month as expected.
The trade dispute and the chance for at least a partial resolution continues to be a key factor in currency markets.
Asian financial markets also tread water as the focus shifted to the U.S. Federal Reserve decision later on Wednesday. The market has priced in 25 basis points U.S. rate cut.
"Fed is likely to maintain some degree of optionality with regard to future policy guidance, without over-committing," Maybank analysts said in a note.
"It (Fed) could possibly go a step further to signal that the mid-cycle adjustment has ended, akin to hawkish cut."
Investors will also await U.S. third-quarter GDP figures, due on Wednesday ahead of the Fed decision. Any weakness in the data could increase worries on global growth.
