Russian Foreign Minister Sergei Lavrov has condemned the “disproportionate” build - up of US weapons and munitions on the troubled Korean Peninsula.Lavrov said during a press conference in Moscow on Tuesday thatthe deployment of missile systems in the area will create a real threat to the region's security and strategic stability. “Russia and China are no less concerned about the desire of individual states to use the difficult situation on the Korean Peninsula to build up their military presence in the region," he said. Lavrov said the US is loading into the region "new weapons, including the most recent weapons, which are so technologically advanced that it is completely disproportionate to the real threat.” Moscow is “very concerned about the situation on the Korean Peninsula,” he said. “It is necessary to do everything to calm it down and to prevent, you know, a negative spiral,” and avoid “engaging in a vicious circle,” Lavrov added. Tensions between North and South Korea have escalated since the start of 2016 after Pyongyang’s nuclear test in January and its long-range rocket launch the next month, followed by harshest sanctions imposed on North Korea. Pyongyang said the rocket launch was aimed at placing an earth observation satellite into orbit. However, Washington and Seoul denounced the move as a cover for an intercontinental ballistic missile test. North Korea has pledged to develop a nuclear arsenal in an effort to protect itself from the US military, which occasionally deploys nuclear-powered warships and aircraft capable of carrying atomic weapons in the region.
