Finland's President Sauli Niiniste and Prime Minister Sanna Marin supported the country's application to join NATO.
The joint statement issued by the Finnish leaders said that NATO membership would strengthen Finland's security. According to the head of government and the president, Finland's incorporation into NATO will increase the defense capability and strengthen the alliance. They also said that Finland should apply to NATO as a matter of priority.
"We hope that the national steps that are still needed to reach this decision will be taken quickly in the coming days," the joint statement said.
At the same time, Finland will be able to officially apply to NATO after this step is approved at a meeting of the ruling Social Democratic Party, which is to be held on May 15, Ilta-Sanomat publication said.
It was earlier reported that Finland and Sweden wanted to submit their applications to NATO at the same time to thus express solidarity between the new applicants.
"Russia will be forced to take retaliatory steps, both of military and other nature, in order to curtail the threats that arise to its national security in this regard,” the Russian Foreign Ministry said in a statement commenting on the possible accession of Finland to NATO.
If Finland joins NATO, Russia will view such a move as a violation of international legal obligations, a message posted on the official website of the Russian Foreign Ministry said.
Moscow has always assured Helsinki that Russia's aggressive actions against Finland would never take place. However, Finland's desire to join NATO comes in violation of the 1947 Paris Peace Treaty, according to which the parties undertook not to enter into alliances and coalitions directed against one of them.
The Foreign Ministry added that Finland also violated the 1992 treaty on the foundations of relations between Moscow and Helsinki. The treaty stipulated that Russia and Finland must "refrain from the use of force against the territorial integrity or political independence of the other party.”
"However, given how the West neglects international law, such behavior has become normal,” the Foreign Ministry concluded.
The British press has recently reported that Russia was going to conduct a nuclear test either on the borders with Ukraine or in the Black Sea.
