Masks will also become compulsory for the first time in Brisbane and some surrounding municipalities, the Queensland state government said.

In other developments in the Asia-Pacific region:

— A state of emergency took effect Friday in and around Tokyo as coronavirus cases surge. Japanese Prime Minister Yoshihide Suga issued the declaration Thursday. It lasts until Feb. 7, and asks restaurants and bars to close at 8 p.m. and people to stay home and not mingle in crowds. The declaration carries no penalties. But it works as a strong request while Japan juggles to keep its economy going. Shopping malls and schools will remain open. Movie theaters, museums and other events will be asked to reduce attendance. Places that defy the request will be publicized on a list, while those that comply will be eligible for aid, according to officials. Suga also promised more aid for hospitals treating COVID-19 patients. The Japanese military is ready to help, and efforts are underway to get a vaccine approved and delivered, he added.
