BEIJING - Dozens of ships from China's East Sea Fleet fired long-range missiles during recent live ammunition drills, state media reported on Friday.
Footage from state television broadcaster CCTV showed some of the Chinese navy's newest ships shooting missiles at targets reported to be several hundred nautical miles away.
Data collected from land, air and sea helped the boats to lock on to their distant targets, state media reported.
The report came as Beijing is locked in an increasingly bitter territorial dispute with Japan in the East China Sea.
Sino-Japanese tensions over a string of Japanese-controlled islands in the East China Sea that are also claimed by Beijing spiked two years ago shortly before Japanese Prime Minister Shinzo Abe took office.
The relationship between China and many of her southern neighbors have also become increasingly fraught over recent months over claims in the South China sea. Anti-China riots in Vietnam erupted after China's towing of an oil rig into waters claimed by both countries in early May.
China claims almost the entire oil- and gas-rich South China Sea, rejecting rival claims to parts of it from Vietnam, the Philippines, Taiwan, Malaysia and Brunei.
