Anti-government protesters in Hong Kong plan to hold a mass rally later Saturday as they face down increasingly stern warnings from China over weeks-long unrest that has plunged the city into crisis.

The semi-autonomous southern Chinese financial hub has seen two months of protests and clashes triggered by opposition to a planned extradition law that quickly evolved into a wider movement for democratic reforms.

Authorities in Hong Kong and Beijing this week signalled a hardening stance, including with the arrests of dozens of protesters, and the Chinese military saying it was ready to quell the ‘intolerable’ unrest if requested.

But protesters have remained unyielding, vowing to hold multiple rallies and marches throughout the weekend and into next week, sending tensions soaring once more.

The first rally is expected to take place in the densely populated suburb of Mongkok, which has previously seen clashes between police and demonstrators.

Two marches are also planned for Sunday — one on Hong Kong island and the other in the Tseung Kwan O district — as well as a city-wide strike on Monday and rallies in seven locations.

Hong Kong has witnessed eight consecutive weekends of huge rallies — often followed by violent clashes between police and small groups of hard core protesters.

Under the terms of the 1997 handover deal, the city has rights and liberties unseen on the mainland, including an independent judiciary and freedom of speech.

But many say those rights are being curtailed, citing the disappearance into mainland custody of dissident booksellers, the disqualification of prominent politicians and the jailing of pro-democracy protest leaders.

Hong Kong chief executive Carrie Lam has made few concessions beyond agreeing to suspend the extradition bill and has made few public appearances.

Protesters are demanding her resignation, an independent inquiry into police tactics, an amnesty for those arrested, a permanent withdrawal of the bill and the right to elect their leaders.
