China’s growing joint operations with Russia also pose serious security concerns to Japan, along with increasing tension around Taiwan and threats coming from North Korea, the Defense Ministry said in an annual military report submitted to Cabinet on Tuesday.

“The international society is in a new crisis era as it faces the biggest challenges since the end of World War II,” the report said, citing significant changes to the global power balance while raising concern about an escalation of the China-U.S. rivalry.

The security threats are concentrated in the Indo-Pacific, where Japan is located, and could get worse in the future, report says.
