On Sunday, North Korea fired a long-range rocket to allegedly place a satellite into orbit, defying UN Security Council resolutions. US President Barack Obama announced that Washington was consulting with Seoul on possibility to expand missile defenses in the Pacific region to counter any potential strike from North Korea.
China and Russia have expressed opposition to the controversial defense system, arguing it could upset the regional balance.
"The sides exchanged opinions on the situation on the Korean Peninsula and in the North-Eastern Asia. Russia expressed concern over information on South Korea's decision to begin talks with the US on deployment of American THAAD missile defense systems on the territory of the country," the ministry said in a statement.
The THAAD system is capable of destroying enemy missiles either before they leave earth’s atmosphere or shortly after the missiles re-enter the atmosphere. The type of missile fired by North Korea is capable of hitting all of South Korea and Japan, as well as the US states of Hawaii and Alaska.
