Not really as there basically is only one big defense treaty in the form of NATO. For it to be similar there would have to be 2 or 3 defense treaties of roughly the same size/strength which Russia does not come anywhere close to.
Russia and China are not allied though. In fact militarily they are against each other due to India. Russia is selling India weapons that India then uses against China in their ongoing border conflict. This is also why India did not really join the sanctions against Russia.
