Hong Kong lawmakers are set to resume a debate on Wednesday over a controversial bill that would make disrespecting China's national anthem a criminal offense, as the city ramps up for fresh protests amid simmering anti-government tensions.

An annual vigil to mark the June 4, 1989, anniversary of Chinese troops opening fire on pro-democracy students in and around Tiananmen Square has been canceled for the first time ever due to the coronavirus, but activists still plan to rally.

The ban comes on the heels of China's plan to directly impose national security laws on Hong Kong, a move that has drawn international condemnation and revived anti-government demonstrations in the former British colony.
