AP News reports that the World Bank cut its economic growth forecast for developing countries in East Asia due to the impact of the coronavirus’s delta variant and called on governments to help the poor and small businesses avoid long-term damage.

Excluding China’s unexpectedly strong growth, developing countries in East Asia should grow by 2.5% this year, down from a forecast of 4.4% in April, World Bank said in a report. It said China, the region’s biggest economy, should expand by 8.5%.

The region is “suffering a reversal of fortune” after China, Vietnam and other governments contained coronavirus outbreaks last year, the bank said. It said business activity in Vietnam, Thailand, the Philippines and other economies was improving but now is “showing signs of slowing down.”

The region must increase vaccine production due to the unreliability of imports and high demand, the bank said. It said governments also need to use testing, tracing and isolation to contain infections and strengthen their health systems.

To prevent long-term economic damage, the bank said governments need to support productive companies and encourage new competitors, promote technology development and reduce trade barriers.
