North Korea condemns drills by U.S., Japan, S. Korea as 'Asian NATO'

The latest joint drills involved Washington's nuclear-powered aircraft carrier USS Theodore Roosevelt, Tokyo's guided-missile destroyer JS Atago, and Seoul's KF-16 fighter jet

North Korea denounced on June 30 joint military drills by South Korea, Japan and the United States, calling them an "Asian version of NATO" and warning of "fatal consequences".

It comes a day after the allies wrapped up three-day exercises, dubbed "Freedom Edge", in ballistic missile and air defences, anti-submarine warfare and defensive cyber training.

U.S., South Korean and Japanese leaders agreed at a trilateral summit last year to conduct annual drills as a sign of unity in the face of North Korea's nuclear threats and China's rising regional influence.

"We strongly denounce... provocative military muscle-flexing against the DPRK," Pyongyang's Foreign Ministry said in a statement carried by the state-run KCNA news agency on June 30, referring to the North's official name.

"The U.S.-Japan-ROK relations have taken on the full-fledged appearance of an Asian-version NATO," it said, warning of "fatal consequences".

"The DPRK will never overlook the moves of the U.S. and its followers to strengthen the military bloc."

The latest joint drills involved Washington's nuclear-powered aircraft carrier USS Theodore Roosevelt, Tokyo's guided-missile destroyer JS Atago, and Seoul's KF-16 fighter jet.

Pyongyang has always decried similar combined exercises as rehearsals for an invasion.

The two Koreas have meanwhile been caught in a tit-for-tat balloon campaign in recent weeks, with Pyongyang sending trash-filled balloons southwards in retaliation to similar missives sent northwards from the South carrying pro-Seoul propaganda.

South Korea has also grown anxious over the North's warming relations with its isolated neighbour Russia.

North Korea is accused of breaching arms control measures by supplying weapons to Russia to use in its war in Ukraine, and Russian President Vladimir Putin held a summit with leader Kim Jong Un in Pyongyang this month in a show of unity.
