There is no such thing as "officially closed". The moment people start shooting there, driving a ship across becomes dangerous. This was an absolutely predictable consequence of the attacks on Iran, you didn't need to wait until several tankers were burning to know these attacks were likely to happen and the strait would become essentially too risky to pass.

Are Russian or Chinese ships actually passing? Junior just released a decree saying not one liter of oil will pass. It didn't have an asterisk allowing Russian or Chinese ships.

I also find it funny that we just decided to allow Russia to pad its coffers by temporarily lifting sanctions on sale of Russian oil. Sorry Ukraine!

The strait is now mined at least partially. Country of origin doesn't matter when there are mines in the water.
