A U.S. training vessel with 225 American naval cadets and 50 of their teachers from the California Naval Academy dropped anchor Monday in the port of Vladivostok in the Russian Far East, Itar-Tass reported. The cadets planned to visit the Far East Naval Academy in Vladivostok to study Russian training methods. They will also tour a fishery institute and deliver humanitarian aid for children, the news agency said.Later this month, a ship carrying 250 U.S. marines and 12 amphibious vehicles will participate in Russian-U.S. naval exercises in Vladivostok devoted to rescue training. The cadets' visit and the June 18-23 exercises come shortly after criticism by nationalist Russian lawmakers resulted in the shelving of plans for 250 U.S. army troops to hold the first joint military maneuvers in Russian in July. The exercises will be held at a base in the United States instead.
