Taiwan foreign minister calls for 'genuine' elections in Hong Kong

Taiwan's foreign minister on Monday called for "genuine" democratic elections to be held in Hong Kong after the city was rocked by fresh political violence, comments that will likely infuriate Beijing.

Hong Kong has been plunged into its worst crisis in recent history by weeks of marches and sporadic violent confrontations between police and pockets of hardcore protesters.

The initial protests were lit by a now-suspended bill that would have allowed extraditions to mainland China.

But they have since evolved into a wider movement calling for democratic reforms, universal suffrage and a halt to sliding freedoms in the semi-autonomous territory.

Police fired tear gas and rubber bullets at protesters on Sunday night, the seventh weekend in a row that the city has witnessed political violence. Separately masked men wielding sticks beat up anti-government protesters at a subway station, putting dozens in hospital.

In a tweet on Monday Taiwan's foreign minister Joseph Wu said it was time for the city's leaders to grant universal suffrage, a core demand of protesters.

"It's sad to see the rule of law eroding and the divide between the people and the government widening in HongKong," Wu said as he accompanied President Tsai Ing-wen in a stopover in Denver on their way back from a visit to diplomatic allies in the Caribbean.

"The way forward is genuine democratic elections, not violence in the streets & MTR stations. The freedom and human rights of the people must be protected!" he added.

Taiwan is gearing up for a presidential election where a dominant issue will be relations with the mainland -- which sees the self-ruled island as its own territory and has vowed to seize it.

Ties with Beijing have deteriorated since Tsai came to power in 2016 because her party refuses to recognise the idea that Taiwan is part of "one China".
