Why Is Iran Allowing India, China, Qatar and Iraq to Pass Through the Strait of Hormuz?

Iran has exempted ships from India, China, Qatar and Iraq from restrictions in the Strait of Hormuz, according to Iranian lawmaker Amir Hayat Moqaddam. He said Iran will receive medicine from India and political support from China, while charging transit fees to Indian and Chinese ships; Qatari vessels pass for free. Qatar already provides diplomatic support to Tehran and is mediating efforts to end the US-Israel war on Iran. The article says it is unclear whether Iraqi ships will pay a toll or how effectively the arrangements work, with the US naval blockade of Iran’s southern ports still in place since July.
