This was conveyed by US national security advisor Jake Sullivan during a telephone conversation with Sri Lanka's National Security Advisor Sagala Ratnayake on Wednesday, the White House said in a brief statement on Friday.

"Their discussion has covered areas of bilateral engagement, including US support to Sri Lanka's security and sovereignty," the statement said.

Sullivan and Ratnayake also discussed Sri Lanka's ongoing efforts to complete the fiscal, monetary, and governance elements of its International Monetary Fund (IMF) programme, and future opportunities for cooperation, the release said.
