WASHINGTON (BLOOMBERG, XINHUA) - President Donald Trump has labelled recent protests in Hong Kong as “riots”, adopting the language used by Chinese authorities and suggesting that the United States would stay out of an issue that was “between Hong Kong and China”.

“Something is probably happening with Hong Kong, because when you look at, you know, what’s going on, they’ve had riots for a long period of time,” Mr Trump told reporters at the White House on Thursday (Aug 1) before departing for a campaign rally in Cincinnati.

He said he does not know what China’s attitude is on the matter.

“Somebody said that at some point they’re going to want to stop that,” Mr Trump said. “But that’s between Hong Kong and that’s between China, because Hong Kong is a part of China.”

In his remarks, Mr Trump signalled that he considered the issue China’s internal matter to resolve. “They’ll have to deal with that themselves,” he said. “They don’t need advice.”

Mr Trump’s hands-off approach to the protests in Hong Kong could bolster the territory’s Beijing-backed government, despite the State Department’s official efforts to defend protesters’ freedom of expression.

Protests erupted outside police stations earlier this week when the Hong Kong government charged 44 demonstrators with a colonial-era rioting crime that carries a sentence of up to 10 years in prison.

China has recently sought to blame the US for crimes committed by some protesters on the front lines of rallies, saying violence was the “creation of the US” and calling the country a “black hand” behind the demonstrations.

Tying the US to the unrest could serve several purposes for Beijing, including discrediting the protesters, rallying mainland sentiment against them and potentially justifying more direct intervention.

On Friday, China urged the US and other countries to immediately stop interfering in Hong Kong affairs in any form, Chinese top diplomat Yang Jiechi said in an interview with Xinhua News Agency.

The US and some other countries have been mixing right and wrong, stirring up trouble during the recent violent incidents over the revision of an extradition amendment Bill in Hong Kong, added Mr Yang, director of the Office of the Central Commission for Foreign Affairs.

"They also arranged for senior officials to meet leading anti-China figures and supported the illegal activities of extreme, violent protesters with the aim of undermining the prosperity and security of Hong Kong," noted Mr Yang, who is also member of the Political Bureau of the Central Committee of the Communist Party of China.

"We strongly urge the US and some other Western governments to abide by international law and basic norms of international relations, adhere to their commitment not to interfere in Hong Kong affairs."

Mr Yang also stressed that the central government will continue to implement the policy of "one country, two systems".
