South Korea summons Russian ambassador over treaty with North Korea

South Korea's foreign ministry said it had summoned the Russian ambassador in protest of a pact between Russia and North Korea signed in Pyongyang this week, as a Reuters witness saw him enter the ministry building on Friday afternoon.

First vice foreign minister Kim Hong-kyun conveyed Seoul's stance on the pact and military cooperation between Russia and North Korea to Georgy Zinoviev, the top Russian envoy to Seoul, Seoul's foreign ministry said.

Kim told Zinoviev that Russia's military support for North Korea harms South Korea's security and would inevitably have a "negative impact" on relations between Seoul and Moscow.

He also urged Russia to "act responsibly," according to the ministry.

South Korea's foreign minister, Cho Tae-yul, and US Secretary of State Antony Blinken have condemned the treaty as a serious threat to regional peace and stability, Seoul's foreign ministry said in a statement on Friday.

The two in a phone call on Thursday also discussed ways to respond to the summit between Putin and North Korean leader Kim Jong Un and agreed to closely monitor the situation, the foreign ministry said.

Blinken said the United States supports South Korea's responses to security threats. Under the pact, Moscow and Pyongyang said each country would provide immediate military assistance if either faces armed aggression.

Cho said any cooperation to help strengthen North Korea's military capabilities is a clear violation of the UN Security Council resolutions, according to the statement.

The United States will consider various ways to respond to the threat to international peace and stability from Russia and North Korea, Blinken was quoted as saying by the ministry.

Cho also spoke on the phone with Japanese Foreign Minister Yoko Kamikawa, and both expressed grave concern over the treaty between Moscow and Pyongyang, according to the ministry.
