The US and China have agreed to resume trade talks, easing a long row that has contributed to a global economic slowdown.

US President Donald Trump and China's President Xi Jinping reached agreement at the G20 summit in Japan.

Mr Trump also said he would allow US companies to continue to sell to the Chinese tech giant Huawei, in a move seen as a significant concession.

Mr Trump had threatened additional trade sanctions on China.

However, after the meeting on the sidelines of the main G20 summit in Osaka, he confirmed that the US would not be adding tariffs on $300bn (£236bn) worth of Chinese imports.

He also said he would continue to negotiate with Beijing "for the time being".

President Trump has positioned his trade talks with Xi Jinping as a win for the US - but he may have also given Beijing exactly what it wants on Huawei.

It is still not clear whether what Mr Trump has announced is a complete reversal - but if it is, it would be a significant concession by the US on a company that Washington has said is a threat to national security.

The resumption of talks and pressing the pause button on more tariffs will be seen in the short term as positive for markets and American businesses. Those have already complained about the cost of further tariffs saying that if they had gone ahead - American consumers would have ended up paying something like $12bn more in higher prices

Chinese businesses have been suffering too - the trade war has hit investment plans, business confidence, and exports in the world's second largest economy. But pressing pause doesn't mean the trade war is over. Tariffs on hundreds of billions of dollars worth of goods are still in place. And the two sides still have much to agree on.

Washington wants Beijing to fundamentally change the way China's economy has grown over the past four decades - get rid of subsidies to state owned companies, open up the domestic market and most importantly, hold China to account if it fails to deliver on any of these commitments.

But Beijing has already publicly said that it won't budge on issues of principle or bow to US pressure.

How the two sides close that gap will be the real test of any trade truce. For now - it is a positive thing that they're talking again. But talking can only take you so far.

How has the US-China trade dispute escalated?

The US and China have been fighting a damaging trade war over the past year.

Mr Trump accused China of stealing intellectual property and forcing US firms to share trade secrets in order to do business in China, which in turn said US demands for business reform were unreasonable.

The feud escalated in the months leading up to the summit, after talks between the two countries collapsed in May.
