Russian and US officials had met on the sidelines of a meeting of the five permanent members of the UN Security Council in Beijing to discuss the fate of the Intermediate-Range Nuclear Forces treaty (INF) — a source of raging tensions between Moscow and Washington.
The United States has warned that it will begin a six-month withdrawal process from the treaty on February 2 unless Russia destroys its 9M729 ground-based missile system, which it says breaches the Cold War-era agreement.
Ryabkov called the US position “rather tough, ultimatum-like” and “destructive,” state news agency RIA Novosti reported.
“We have not made any progress. We state this not just with sorrow, but with deep concern for the fate of the treaty, for the fate of European and international security,” Ryabkov said.
Last week the Russian military displayed the nuclear-capable 9M729 missile system to the media and foreign military officials in an attempt to prove the weapon does not violate the treaty.
Russia says the missile’s maximum range is 480 kilometres (300 miles) and within the allowed range.
Washington has however said a static display of the cruise missile does not prove its range does not breach the agreement.
Signed in 1987 by US president Ronald Reagan and Soviet leader Mikhail Gorbachev, the INF treaty bans ground-launched missiles with a range of 500 to 5,500 kilometres.
It ended a dangerous build-up of warheads in Europe but there are fears a similar situation could re-emerge.
US officials have said that if Russia misses the February 2 deadline, the Pentagon will begin work on its own missile system that would otherwise be barred by the treaty.
Russia has said that because Washington’s claims are unsubstantiated the agreement would remain in force even if the US tries to withdraw.
