Trump says China 'very spoiled' by trade wins over US

"Our high level delegation is on the way back from China where they had long meetings with Chinese leaders and business representatives," Trump wrote in a tweet.

"We will be meeting tomorrow to determine the results, but it is hard for China in that they have become very spoiled with US trade wins," he added.

The American president has accused China of unfair trade practices that have driven up the US goods deficit with the Asian giant. Washington has also alleged "theft" of American intellectual property by China.

The discussions promised a potential off-ramp for the trade conflict. Trump has threatened to levy new tariffs on $150 billion of Chinese imports while Beijing shot back with a list of $50 billion in targeted US goods.

"Both sides recognise there are still big differences on some issues and that they need to continue to step up their work to make progress," China said in a statement released by the official Xinhua state news agency.

"The two sides exchanged views on expanding US exports to China, trade in services, bilateral investment, protection of intellectual property rights, resolution of tariffs and non-tariff measures."

It added that they had reached "a consensus in some areas", without elaborating. The agency said both sides had agreed to establish a "working mechanism" to continue talks.

Beijing has promised reform on several fronts in recent months -- including lifting foreign ownership restrictions for automakers and allowing foreign investors to take controlling stakes in financial firms.

But a list of US demands presented at the talks in Beijing showed these steps fall far short of expectations in Washington.

The demands included cutting China's trade surplus with the US by at least $200 billion by the end of 2020, lowering all tariffs to match US levels, eliminating technology transfer practices, and cutting off state support for some Chinese industries, according to Bloomberg News.

The White House called the discussions "frank" while making no mention of continuing the negotiations.

"There is consensus within the Administration that immediate attention is needed to bring changes to United States–China trade and investment relationship," a White House statement said.
