Britain and US have today agreed to resolve a long-running trade dispute over Airbus and Boeing and turn their attention to tackling Chinese subsidies, echoing a five-year tariff truce announced by Washington and Brussels.

Together, the matching deals draw a line under 17 years of battles at the World Trade Organization over aid for the world's largest planemakers.

They also establish a common front against "non-market" funding, in a reference to China's rising aerospace sector.

The dispute had triggered a months-long transatlantic tariff war hitting industries such as Scotch whisky until the punitive measures were suspended earlier this year to ease negotiations.

Tariffs will now be set aside for a further five years while governments pledge to provide any funding on market terms.

But the two UK-US and EU-US agreements effectively lift uncertainty over a key source of transatlantic trade tensions.

"This will support jobs across the UK and is great news for Scotch whisky and other exports including aerospace who will no longer face punitive tariffs," British trade minister Liz Truss said.

The Scotch Whisky Association welcomed the deal and said its members had lost £600m because of US tariffs of up to 25% imposed between October 2019 and March this year.

In the US, the Distilled Spirits Council said American Whiskey was still being hurt by 25% tariffs in Britain and the EU over a separate dispute on steel and aluminium.

The UK-US aerospace deal came two days after the EU reached a truce with Washington over aircraft subsidies, suspending for five years one set of Trump-era tariffs that had soured relations.

The two sides had been battling since 2004 at the World Trade Organization over subsidies for US planemaker Boeing and European rival Airbus, which each claimed to have been damaged by unfair competition.

Britain has since left the European Union and today's almost identically worded agreement achieves many of the same results as the EU-US deal.

Britain, whose ability to negotiate trade deals independently of the EU is central to its new "global Britain" stance, has a long history as one of four core nations involved in Airbus, a relationship that predated its EU membership, and its UK factories make the wings for Airbus commercial jets.

In December, Britain and the US came close to a standalone aerospace deal that could have forced the hand of Brussels in its own talks with Washington, but drew back amid concerns over UK jobs, Reuters reported.

An official familiar with the talks said it had not been possible at that time to reach a balanced deal.

Airbus, which has 14,000 staff in Britain, has repeatedly warned the UK of the risk that it could shift work abroad, restricting Britain's ability to negotiate independently over aerospace.
