The second round of talks took place in Washington on May 19-22, involving Vietnam’s trade minister Nguyen Hong Dien and the US trade representative Jamieson Greer, the Vietnamese ministry said on its website, showing pictures of meetings.

“At the end of the negotiation round, Vietnam and the US made positive progress, identifying groups of issues on which consensus was close, and groups of issues that needed further discussion to reach consensus in the coming time,” the statement said, without elaborating.

It noted that talks will need to continue in early June.

The US trade representative did not immediately reply to a request for comment outside of US business hours.

Vietnam heavily relies on exports to the US and faces one of the highest “reciprocal” tariff rates set by the White House at 46%.

Those duties have been paused globally by Washington until July.
