"On June 15, 2016, the Latvian government renewed the work of the Latvian task group. It is ready to continue negotiations with Lithuania," the ministry said in a response to a question from the Lithuanian daily Lietuvos Žinios.

Lithuania and Latvia have failed to legitimize their maritime border for a quarter of a century now. The Latvian parliament has not yet ratified a maritime border agreement with Lithuania that was signed more than a decade ago.

It is thought that the Latvians are stalling the process because of oil deposits believed to be available in the Baltic Sea area.
