He said 600,000 doses of the Chinese vaccine Sinopharm were received and they would be used to inoculate the Chinese workers currently in the island nation.

China recently donated 600, 000 doses of the vaccine to Sri Lanka at the request of President Gotabaya Rajapaksa.
However, no final decision has been taken on administering the Sinopharm vaccine to Sri Lankan national as it is yet to receive approval from the National Medicines Regulatory Authority (NMRA).
