The United States will respect tariff caps in trade deals struck with the European Union, Japan and other countries, and planned US tariffs over forced labour provide the legal basis to do so, US Trade Representative Jamieson Greer says.
"We understand that a deal is a deal," Greer told reporters on the sidelines of an OECD ministerial meeting in Paris on Thursday.
The US has struck deals with the EU and Japan that limit US tariffs on most EU or Japanese imports to a maximum of 15 per cent.
