Russia is accusing NATO of slipping back into Cold War thinking by suspending cooperation with Russia over its seizure of Ukraine's Crimea region.
Russia's NATO envoy Alexander Grushko wrote on his Twitter page Wednesday that NATO's basic Cold War instincts have woken up.
NATO foreign ministers continue their talks in Brussels Wednesday on the crisis in Ukraine.
The ministers decided Tuesday to to officially end all civilian and military cooperation with Russia. They said they do not recognize its annexation of Ukraine's Crimean peninsula and urged Russia to immediately comply with international law.
Diplomatic channels between NATO and Moscow remain open.
Meanwhile, Russia is accusing U.S. banking giant J. P. Morgan of illegally blocking a cash transfer from its embassy in Kazakhstan to a Russian company.
A Russian Foreign Ministry statement calls J.P. Morgan's move "unacceptable, illegal and absurd" and warns the blockage will "have consequences" for the U.S. embassy in Russia.
The ministry linked the blockage to White House sanctions slapped on Moscow for its takeover of Crimea.
The U.S. Congress officially approved the sanctions Tuesday along with final approval to $1 billion in loan guarantees to the Ukrainian government.
