Yellen told a news conference there has been "very substantial progress" on three of the four areas under discussion by the 14 IPEF member countries, but there are "remaining issues" on trade. She said there had been "significant progress" on the trade pillar, "but it looks not to be complete, like something that is likely to require further work." People familiar with the talks said that an announcement of outcomes is more likely on clean energy cooperation and anti-corruption pillars of the IPEF. Both agreed that the U.S. and China should seek fair trade relations and a level playing field on which their companies can compete, Yellen added.
