TOKYO: Japan spotted Chinese vessels sailing near disputed islets in the East China Sea for a record 216 consecutive days, Tokyo鈥檚 coast guard said Sunday.
The Tokyo-administered islands, known as the Diaoyu in China and Senkaku in Japan, have long been a sore point between the neighbors.
On Sunday, Japan said it observed four Chinese coast guard vessels sailing in the 鈥渃ontiguous鈥� zone, referring to a 12-nautical-mile band that extends beyond Japan鈥檚 territorial waters.
Last year, Chinese vessels sailed near the Tokyo-administered island chain a record 355 times, including for a period of 215 consecutive days, a Japanese coast guard spokesman told AFP.
Japanese officials regularly protest the presence of the Chinese coast guard and other vessels in the waters surrounding the remote, disputed islands.
Relations between Japan and China were strained by Tokyo鈥檚 decision to 鈥渘ationalize鈥� some of the islands in 2012.
On Friday, Japan鈥檚 coast guard and its US and Filipino counterparts staged joint training drills off Japan鈥檚 southwest shore 鈥� the second time the countries鈥� coast guards have held training drills together, and the first in Japan.
Territorial disputes with China have pushed Japan to forge deeper ties with the Philippines and the United States.
Earlier this month, Tokyo and Beijing traded barbs over close encounters between their military planes over the Pacific high seas.
