Cambodia said on Sunday it has asked the International Court of Justice to resolve its border disputes with Thailand, after a flare-up in the long-running row led the Southeast Asian neighbours to mobilise troops on both sides of the border.

Cambodian and Thai officials on Sunday (June 15) concluded their "open and positive" negotiations over border issues, said press releases from both countries.

After a deadly border incident and inconclusive talks, Cambodia is now unilaterally appealing to the International Court of Justice.
