Indonesia will launch on Friday emergency measures aimed at controlling its worst coronavirus epidemic since the start of the pandemic, with the curbs due to run until July 20, a senior minister has said.

The world's fourth most populous country has reported a series of record daily Covid-19 cases over recent weeks, including 21,807 infections recorded on Wednesday.

Economic Affairs Minister Airlangga Hartarto said that the health protocols would be applied using law enforcement. He did not provide details but a government document reviewed by Reuters said the measures will be applied on the islands of Java and Bali.

In a bid to halve the current daily cases to below 10,000, Indonesia is proposing tighter restrictions on movement and air travel, a ban on restaurant dining and closure of non-essential offices, according to the government document seen by Reuters.
