COLOMBO, Jan. 10 (Xinhua) -- Sri Lanka's economic recovery is expected to continue in 2019 due to infrastructure development and the GDP is expected to grow 4 percent, the World Bank said in a report on Thursday.

In its annual flagship report for 2019 "Global Economic Prospects: Darkening Skies", the World Bank said that Sri Lanka's economic growth however, is expected to lag behind other countries in South Asia except Afghanistan.

Sri Lanka's economy grew 3.9 percent in 2018 due to a recovery in the agriculture and services sectors while the island's recovery from adverse weather conditions is expected to continue in 2019.

"Activity will be supported by robust domestic demand as consumption rebounds following natural disasters, and investment is boosted by infrastructure projects," the World Bank said.

The World Bank further estimated Sri Lanka's annual GDP growth at 4.1 percent in 2020 and the year following.
