Japan is looking into reviewing its car safety standards as the country seeks to strike a trade deal with U.S. President Donald Trump, Japanese business daily Nikkei reported on Sunday.

The report comes after Japan’s chief negotiator Ryosei Akazawa kicked off tariff discussions with U.S. counterparts in Washington last week. Preparations are under way for a second round of negotiations.

U.S. carmakers have long complained about perceived non-tariff barriers blocking access to Japan’s market, including stringent safety standards. A report by the U.S. Trade Representative last month cited Japan’s non-acceptance of U.S. safety standards certification as providing an equal level of protection as its own standards, unique testing protocols and obstacles to establishing distribution and service networks.
