Iran’s parliament is set to vote on a bill that would formalize the country’s management of the Strait of Hormuz, a senior lawmaker said Saturday.

Alaeddin Salimi, a member of the parliament’s presiding board, said lawmakers had made a “definitive decision” to codify the management of the strategic waterway.

“The parliament’s decision to legislate the management of the Strait of Hormuz is final, and this plan will become law,” Salimi told Iran’s semi-official Tasnim News Agency.

He said the parliament would not allow foreign powers to dictate policy regarding the strait.

“Those who say the Strait of Hormuz must remain open should know that this issue concerns us. We will not allow others to decide for us,” he said.
