Iran and China signed an agreement for long-term economic cooperation over the weekend that had been in the works for years. The deal gives China a stronger presence in one of the most populous countries in the Middle East and gives Iran a lifeline as it continues to battle US economic sanctions.

The signing by the foreign ministers of Iran and China created a stir both on social media and regular news outlets, so much so that Iranian media outlets wrote a number of explanations and clarifications.

Tasnim New Agency wrote an article titled “8 answers to questions about the agreement between China and Iran.” It stated that the agreement dates back to 2016 when the Iranian and Chinese presidents announced in a joint statement in Tehran plans to form a 25-year agreement. In a meeting with China’s president, Supreme Leader Ayatollah Ali Khamenei — who makes final decisions on all state and foreign policy matters — expressed support for the joint statement.

Many observers saw this agreement as a blow to the United States in its efforts to isolate Iran. The United States exited the nuclear deal between Iran and the five permanent members of the UN Security Council plus Germany and Iran in 2018. President Joe Biden has expressed a desire to reenter the deal and even sign an extended deal, but Iran is demanding the United States lift sanctions first before they return to full compliance with the original deal known as the Joint Comprehensive Plan of Action. Either way, the article, citing Iran’s foreign minister, said the deal was not signed with any third parties in mind.
