In this episode, Sal Mercogliano - a maritime historian at Campbell University (@campbelledu) and former merchant mariner - discusses the current situation in and around the Red Sea and should the US continue to protect ships in the region or shift and focus on US-flagged or allied vessels.
His conclusion is that the US is losing as NATO ships are still avoiding the Suez Canal transit while BRICS countries identify themselves as such on the transponder to sail through. 
Are BRICS ship able to use the Suez canal? I would think that even if the Yemeni were targeting only genocide supporters, no ship would use that route for simple insurance reasons (like pretty sure every insurance company notified the shipping companies that the policy is null if something happens while on the Red Sea).
yes, china uses it still. so do countries like sudan, egypt, saudi, liberia, russia, india, etc.
plenty of the open information is even listing publicly the crew's nationality, whole crew being muslim, indians with no contact to israel, number of armed guards, etc as their destination. because yemen is tracking all ship locations
The Houthi have attacked at least one Chinese ship, but I don't know the circumstances of that. It's specifically Russian and Chinese ships that are otherwise getting through safely. I'm not sure how maritime insurance rates have changed for them but it's like 10x for the west.
it seemed to be some sort of communications mix up, ships have started listing their crews in their destination to avoid further issues
I don't know if it's the one you're thinking of, but there was one registered in Hong Kong that got hit - but on closer inspection, it had been owned by a British company before being 'sold' to a Hong Kong shipping company... that had opened a couple of weeks earlier and only had that one ship. So in fact, it shows the detail of the intelligence used by Yemen to select targets that they were able to see through that ruse.
Looking it up, this was the Chinese-owned but Panamanian-flagged MV Huang Pu.
