HONG KONG - China lashed out at Taiwan on Monday over its offer of political asylum to participants in Hong Kong's pro-democracy protest movement, a day after hundreds of thousands of people marched peacefully in the latest massive demonstration in the Chinese territory.

The government of Taiwan, a self-ruled island that China considers its own territory, strongly supports the protests, and Hong Kongstudents in Taiwan held events over the weekend expressing their backing. Taiwan's president made the asylum offer last month, though it's not clear if requests have been received.

Taiwan lacks a formal legal mechanism for assessing and granting asylum requests, although it has granted residency to several vocal opponents of the Chinese government.

On Monday, Ma Xiaoguang, spokesman for the Chinese Cabinet's Taiwan Affairs Office, said Taiwan's offer would 鈥渃over up the crimes of a small group of violent militants鈥 and encourage their 鈥渁udacity in harming Hong Kong and turn Taiwan into a 鈥漢eaven for ducking the law.鈥

Ma demanded that Taiwan's government 鈥渃ease undermining the rule of law鈥 in Hong Kong, cease interfering in its affairs and not 鈥渃ondone criminals.鈥

Organizers said at least 1.7 million people participated in Sunday's Hong Kong rally and march, although the police estimate was far lower. Police said the protest was 鈥済enerally peaceful鈥 but accused a large group of people of 鈥渂reaching public peace鈥 afterward by occupying a major thoroughfare and using slingshots to shoot 鈥渉ard objects鈥 at government headquarters and pointing lasers at police officers.

The protests have at times been marked by violent clashes with police, who say they have arrested more than 700 participants since the demonstrations started in June. However, law enforcement officers kept a low profile Sunday, with no riot police seen from the procession's main routes. When stragglers convened outside a government complex in the late evening, other protesters urged them to go home.

More protests are planned for the coming weeks, with various rallies organized by accountants, transport workers, high school students and relatives of police officers.

Demonstrators' frustrations over what they perceive to be the government's refusal to respond to their demands boiled over last week with the occupation of Hong Kong's international airport, during which a reporter for a Chinese Communist Party-owned newspaper was assaulted, and attacks on a number of police stations.

A former British colony, Hong Kong was returned to Beijing in 1997 under the framework of 鈥渙ne country, two systems,鈥 which promised residents certain democratic rights not afforded to people in mainland China. But some Hong Kongers have accused the Communist Party-ruled central government of eroding their freedoms in recent years.

The protest movement's demands include the resignation of Hong Kong leader Carrie Lam, democratic elections and an independent investigation into police use of force.

Asked Sunday about the situation in Hong Kong, U.S. President Donald Trump said the use of Chinese troops to put down the protests - similar to the bloody crackdown on protesters in Beijing's Tiananmen Square in 1989 - would worsen the current U.S.-China trade dispute.

鈥淚 mean if it's another Tiananmen Square, I think it's a very hard thing to do if there is violence,鈥 Trump told reporters in New Jersey. 鈥淚 think there'd be tremendous political sentiment not to do something.鈥

Trump had originally said the protests were a matter for China to handle but has since suggested that Chinese President Xi Jinping could resolve the situation by meeting with protest leaders.

Chinese foreign ministry spokesman Geng Shuang avoided commenting on Trump's remarks directly, but referred to the president's previous statements on the protests.

鈥淲e have noticed that President Trump has previously stated that Hong Kong is part of China, and that they must solve it themselves and do not need advice. We hope that the U.S. side can match its acts to its words,鈥 Geng told reporters at a daily briefing.

China has furiously rejected all outside calls for it to discuss protesters' demands.

Members of China's paramilitary People's Armed Police force have been training for days across the border in Shenzhen, including on Sunday morning, fueling speculation that they could be sent in to suppress the protests. The Hong Kong police, however, have said they are capable of handling the demonstrations.
