On 27 March 2021 Iran and China signed a 25-year comprehensive cooperation agreement covering energy, infrastructure, and security-adjacent cooperation. Khamenei had publicly endorsed looking East.

Context

Rouhani’s foreign ministry signed. Neighbouring JCPOA was already reduced. He did not sit as a CNPC engineer.

JCPOA reductions 2019 are neighbouring. Xi’s 2023 Saudi brokerage is later.

The Supreme Leader of Iran is commander-in-chief and the highest constitutional authority. He does not write a US presidential strike order, an IAEA Board resolution, or a Hamas military plan. Presidents, the IRGC, and the Guardian Council implement and share specific files.

Why it matters

The path is industrial policy and sanctions: a completed long-horizon partnership is a dated sanctions-hedge instrument.

What the sources establish

Office of the Supreme Leader of Iran carries the official instrument or communique. Reuters records the same dated act independently.

Established: 27 March 2021 Iran–China 25-year agreement, independently reported.

Not established: a unique later investment coefficient from that day, or that sanctions ended.

The foreign ministry signed. China signed.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Iran and China sign a 25-year comprehensive cooperation agreement, not a later speech about Iran and China sign a 25-year comprehensive cooperation agreement.

Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He endorsed the East turn. The foreign ministry signed. China signed. That limit is the alternative to treating office-holding as authorship of every later series.
