Like the USA, I don't think Russia codifies treaties into law. Like in the USA, treaties for Russia are mere suggestions used as a geopolitical tool until inconvenient.
This does not follow my understand of treaties signed and ratified by the US.
> Domestic Enforcement: If the treaty is self-executing, its provisions automatically become part of federal law under the Constitution’s Supremacy Clause. If it is non-self-executing, Congress must draft and pass implementing legislation to establish domestic enforcement.
I know much less about treaties signed and ratified by Russia, but I found this:
> Russia codifies international treaties into domestic law through the formal ratification process. Under Article 15(4) of the Constitution of the Russian Federation, ratified treaties are considered an integral part of the Russian legal system, provided they do not conflict with domestic constitutional principles.
