MOSCOW, 06 January 2021, (TON): The Russian Foreign Ministry made US responsible for Iran's recent decision of enriching uranium to 20 percent.

The Iranian move was "a deviation" from the Joint Comprehensive Plan of Action (JCPOA), commonly known as the Iran nuclear deal, but the "root cause" of such deviations is the "systematic gross violations" of international obligations by the US, the ministry on Tuesday said in a statement.

Contrary to Article 25 of the UN Charter, the US does not comply with the UN Security Council Resolution 2231 and deliberately creates obstacles to its implementation for other countries, the ministry said.

According to Moscow, enriching uranium to 20 percent has nothing to do with Iran's compliance with the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).

All material enriched up to 20 percent is under the control of the International Atomic Energy Agency, which does not record its switch to the use for undeclared purposes that go against the NPT, the statement read.

In May 2018, Washington pulled out of the Iranian nuclear deal and reimposed harsh sanctions against Iran. In response, Tehran has gradually dropped some of its JCPOA commitments since May 2019.
