CHENGDU, China (Reuters) - U.S. Treasury Secretary Jack Lew said commitments by G20 members to refrain from competitive currency devaluations have helped sustain economic confidence, according to a statement summarizing discussions between Lew and Japanese Finance Minister Taro Aso.

The two were speaking during the G20 meeting of finance ministers and central bank governors in Chengdu, China on Saturday.

Lew also "reinforced the importance" of working quickly to approve and implement the Trans-Pacific Partnership agreement, the press release said.
