The U.S. is planning to relocate its X-band radar on the Kwajalein Atoll in the Pacific to the Czech Republic as part of its proposed European missile shield, which will also include deploying 10 interceptor missiles in Poland.
"We believe these plans contain risks that will destabilize the situation and create demarcation lines. We will try to reduce these risks if we cannot stop them," Lavrov said.
The Russian diplomat said earlier this month that Washington could ease Moscow's concerns "by not deploying missile defenses in Europe."
The Pentagon's deployment plans in Central Europe continues to be a major bone of contention in relations between the U.S. and Russia, which considers the project a threat to its national security. Washington has proposed a range of measures to ease Russian concerns.
However, Russia has insisted on the permanent deployment of Russian personnel at the facilities in Poland and the Czech Republic. Agreement has yet to be reached on the issue.
