Just three days before US President-elect Donald Trump returns to the White House, Russia and Iran are set to finally sign a “comprehensive partnership agreement,” a deal that’s been in the works for months.

Russian President Vladimir Putin and his Iranian counterpart, Masoud Pezeshkian, signed a broad cooperation pact Friday as their countries deepened their partnership in the face of 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.
