MOSCOW (AFP) - Withdrawing from a Cold War-era nuclear weapons treaty with Russia as President Donald Trump has announced he plans to do is a dangerous step, Russia's deputy foreign minister warned on Sunday (Oct 21).
"This would be a very dangerous step that, I'm sure, not only will not be comprehended by the international community but will provoke serious condemnation," deputy foreign minister Sergei Ryabkov told the Tass state news agency.
The treaty is "significant for international security and security in the sphere of nuclear arms, for the maintenance of strategic stability," he stressed.
Russia condemned what he called attempts by the US to gain concessions "through a method of blackmail", he added.
If the US continues to act "clumsily and crudely" and unilaterally back out of international agreements "then we will have no choice but to undertake retaliatory measures including involving military technology," Ryabkov told RIA Novosti news agency.
"But we would not want to get to this stage," he added.
On Saturday, Trump announced US plans to leave the three-decade-old Intermediate-Range Nuclear Forces Treaty, known as the INF, signed in 1987 by the then US president Ronald Reagan.
"We're the ones who have stayed in the agreement and we've honoured the agreement, but Russia has not unfortunately honoured the agreement, so we're going to terminate the agreement and we're going to pull out," said Trump.
But Ryabkov on Sunday denied Trump's accusations, throwing the accusation back at Washington.
"We don't just not violate (the treaty), we observe it in the strictest way," he insisted.
"And we have shown patience while pointing out over the course of many years the flagrant violations of this treaty by the US itself."
US National Security Adviser John Bolton is set to arrive in Moscow on Sunday.
"We hope that we will hear from him during meetings, tomorrow and the day after, more substantively and clearly what the American side intends to undertake," said Ryabkov.
Earlier a foreign ministry source told Russian news agencies that the US move was connected to its "dream of a unipolar world", an argument that Ryabkov also advanced.
"Apparently the existence of the Intermediate-Range Nuclear Forces Treaty creates problems for establishing a line of total US domination and supremacy in the military sphere," he said.
TIES UNDER STRAIN
A US withdrawal from the INF could also target China. As a non-signatory, Beijing can develop without constraints intermediate-range nuclear weapons.
US-Russia ties are under deep strain over accusations that Moscow meddled in the 2016 presidential election, as well as tension over Russian support for the Syrian government in the country's civil war, and the conflict in Ukraine.
On Friday, the finance chief of Russia's leading troll farm was indicted in the US for interfering with US elections, the first person to face charges involving the 2018 congressional midterm vote.
Russia accused the US of fabricating the charges.
Washington is, however, looking for support from Moscow in finding resolutions to the Syria war and putting pressure on both Iran and North Korea.
No new summit between Trump and Putin has been announced, but one is expected in the near future.
The two leaders will be in Paris on Nov 11 to attend commemorations marking the end of World War I.
A senior Trump administration official, who spoke on condition of anonymity, said another potential date would be when the presidents both attend the Group of 20 meeting on November 30 to December 1.
