Diplomatic efforts around the Strait of Hormuz continue, with China, the U.N. and maritime bodies urging restraint as U.S. deadline pressure increases.

Diplomatic efforts to calm the crisis around the Strait of Hormuz intensified on April 4 and remained active Sunday as new reporting added sharper U.S. pressure.

AP reported that China put forward a five-point proposal aimed at de-escalation around the waterway. The U.N. warned the crisis could widen if tensions keep rising, and maritime bodies urged caution for shipping near the strait.

The latest confirmed reporting also adds a U.S. deadline element, with Trump pressing Iran to reopen the waterway. That makes the diplomacy more urgent, even as officials continue to warn that military escalation could spill further into the region.

The core message from the major institutions is the same: avoid steps that could turn a shipping dispute into a broader war.

For now, the question is whether any of the diplomatic channels can slow the pace of escalation before the deadline window closes.
