"Today, together with the Chinese colleagues, we requested a meeting of the UN Security Council in connection with US statements about its plans to test and deploy medium-range missiles," Polyanskiy said.
Polyanskiy added that the council’s meeting is scheduled to take place on Thursday.
In February, the United States formally suspended its obligations under the Intermediate-Range Nuclear Forces (INF) Treaty, which required that the United States and Russia eliminate and permanently forswear all nuclear and conventional ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometres (310-3,417 miles). This triggered a six-month withdrawal process, which was completed on August 2. As a response to Washington's actions, Russian President Vladimir Putin signed a decree in July suspending his country's participation in the accord. This came after both sides accused each other multiple times of violating the INF.
