Newsweek:
A foreign submarine spotted cruising through waters around disputed islands in the East China Sea last week was actually a Chinese nuclear missile attack submarine, Japan said on Monday.
Itsunori Onodera, Japan’s defense minister, told reporters that the unidentified submarine was “China’s Shang-Class nuclear-powered attack submarine,” a vessel that is able to carry several long-range cruise missiles and torpedoes.
“Nuclear-powered submarines can also cruise for long hours and it is more difficult to detect them because they dive deep,” Onodera said. “We have serious concerns as the submarine’s underwater passing through our country’s contiguous waters is an act that unilaterally increases tension.”
