Speaking after a meeting with Japanese counterpart Taro Kono, Sergei Lavrov said: “If the British government continues taking some anti-Russian measures, we will hit back under the principle of reciprocity.”
Lavrov urged the British government to “respond calmly” over the March 4 attack on former spy Sergei Skripal and his daughter Yulia, who remain in critical condition.
Britain says only Russia had the capability, motive and intent to be behind the attack, which used the nerve agent Novichok reportedly developed by the former Soviet Union.
Russian President Vladimir Putin has dismissed this as “nonsense”.
Britain reacted by expelling 23 Russian diplomats and their families — around 80 people in total — and has also cut off high-level contacts.
A spokesman for Prime Minister Theresa May said London was “actively considering” other measures.
On Tuesday, the head of the OPCW chemical watchdog said it would take two to three weeks to complete laboratory analysis of samples taken from the poisoning.
The affair has further damaged Russia’s already shaky relations with many Western countries.
The EU has expressed its solidarity with Britain and leaders at a summit later this week will agree to “coordinate on the consequences” for Russia, according to a draft statement seen by AFP.
US Defense Secretary Jim Mattis suggested on Tuesday that Moscow’s suspected involvement shows Russia has “chosen to be a strategic competitor.”
However, President Donald Trump skipped the issue when congratulating Putin on his re-election and proposed a summit in the “not-too-distant future.”
Japanese Prime Minister Shinzo Abe voiced “outrage” over the attack in a call to May, according to her office.
Skripal, 66, a former Russian officer who sold secrets to Britain and moved there in a 2010 spy swap, remains in a coma along with his 33-year-old daughter after they were found unconscious on a bench in Salisbury.
Turning to bilateral issues, Lavrov voiced concern over Japan’s plan to introduce a US land-based Aegis missile defence system, which he said would “directly” affect Russian security.
“We have already handed in a list of Russian concerns to the Japanese side and proposed to set up a special channel of dialogue on this issue,” said Lavrov.
Kono responded that the missile defence system was “purely a defensive one managed by our country independently.”
“It will not be a threat to our neighbour countries, including Russia,” stressed the minister.
