Members of the Russian FSB Border Guard Service and the US Coast Guard have carried out joint exercises patrolling the state border in the Bering Sea waters.

The patrol was performed by the Russian ship Sakhalin and the American ship Alex Haley. The crew members performed radio communication drills, including coordination with a deck helicopter, and practiced using the international code of signals during joint maneuvering.

"No violators were spotted fishing illegally for aquatic biological resources in the area along the demarcation line of the two countries' waters during the joint patrol of the area," the press service of the FSB Border Directorate for the eastern Arctic region said.

The Alaska and Kamchatka border guards signed an agreement on cooperation in protecting aquatic biological resources in the convention area in 1996. The cooperation involves efforts to prevent the violation of fishing rules, control over customs declaration of fishing catches, and protection of the Northern Sea Route between Chukotka and Alaska.

The FSB Border Directorate for the Eastern Arctic Region patrols more than 20,000 km of state border, or one-third of the entire border of Russia.
