モスクワ条約
After the shootdown of the Russian Sukhoi Su-24 over the Syria–Turkey border in November 2015 and the rise of Russian–Turkish tensions, members of the Communist Party of Russia proposed annulling the Treaty of Moscow. Initially, the Russian Foreign Ministry considered that action to send a political message to the government of Turkish President Recep Tayyip Erdoğan. However, Moscow ultimately decided against the idea in its effort to de-escalate tensions with Ankara.
