In what can be called the second incursion by its warship, a Chinese spy ship on Wednesday briefly entered Japanese territorial waters off an island in the southwestern prefecture of Kagoshima in the wee hours, a Japanese official said. As China pushes its territorial claims in the South China Sea America and Japan prep themselves up by exhibiting its naval power. However, Beijing views access to Pacific as seminal for the supply line to the rest of the world's oceans and also for the projection of its naval power.
Earlier, in 2004 a Chinese nuclear submarine had entered the territorial waters near the Sakishima Islands in Okinawa Prefecture. This time the Chinese spy ship had been spotted by a Japanese patrol plane around 3:30 a.m.
Considering the security issues, the Japanese government now plans to take to take all possible measures for warning and surveillance activity for its territorial waters and airspace.
In this regard, Japan had summoned the Chinese ambassador to express concern after a Chinese navy ship sailed close to what Japan considers its territorial waters in the East China Sea.
