July 19 (Asia Today) -- North Korea is intensifying engagement with China and Russia as South Korea, the United States and Japan broaden their cooperation to include the overseas deployment of small modular reactors.

The diplomatic activity follows events marking the 65th anniversary of the North Korea-China Treaty of Friendship, Cooperation and Mutual Assistance.

North Korea received a senior Chinese delegation for the anniversary and dispatched Foreign Minister Choe Son Hui to Russia, signaling efforts to manage relations with both of its principal partners.

The moves are widely viewed as an attempt to strengthen alignment among North Korea, China and Russia as Seoul, Washington and Tokyo expand their security and economic cooperation.
