Vietnam has “essentially completed” talks on a US trade deal and submitted its final remarks to Washington after months of negotiations over tariffs and other trade barriers.

US customs officials have carried out spot inspections on China-linked factories in Vietnam, according to people familiar with the matter, adding to concerns the White House may soon find reasons to pile more tariffs on the Southeast Asian nation.

The US wants Vietnam to take more action on non-tariff barriers, economic security cooperation and intellectual property as the two sides continue to wrangle over a trade deal after months of negotiations, according to the US Trade Representative.
