The presidents of Russia and Iran have held talks in the Kremlin before the signing of a broad cooperation pact to deepen their partnership amid stinging Western sanctions.

The agreement is focused more on trade than military issues, but it will bring two countries with a shared desire to challenge the West closer together.

Russia signed a strategic partnership treaty with Iran on Friday that follows similar pacts with China and North Korea. All three countries are adversaries of the United States, and Russia has used its ties with them to help blunt the impact of Western sanctions and boost its war effort in Ukraine.
