Iranian MP Ebrahim Rezaei says no negotiations will begin until the US fulfils its commitments in the Islamabad understanding, while he stated that Iranian diplomats lack permission for bilateral or trilateral talks in the current situation

The operative question is sequencing: Tehran is demanding performance first, while Washington has historically preferred concurrent or reciprocal steps, and that gap has tended to be where these processes stall. The speaker is a parliamentarian rather than the executive or foreign ministry, and in the Iranian system formal negotiating mandates sit with the Supreme National Security Council and the Supreme Leader's office, so an MP's statement is signalling rather than decisive; the tell is whether official diplomatic channels echo the same condition. The blocked-funds mechanism matters directly to crude only insofar as it governs whether Iranian barrels return to the market under any understanding, so the transmission channel is supply expectations and the prompt structure rather than the rhetoric itself. Worth observing is any US response on the funds question and whether backchannel or intermediary contacts continue despite the public line, since public hardening alongside quiet contact has been the usual pattern.
