President Donald Trump on Thursday destabilized a global effort to limit mining in the deep sea, signing an executive order on Thursday that could eventually open up international waters to excavation firms that the United States unilaterally deems worthy.
The US hasn’t ratified UNCLOS, so in terms of international law, it’s not bound by anything, though Executive Branches in the US have generally acted as if they are bound. Trump, on the other hand, doesn’t even pay much attention to internal US conventions and rams right up against what’s legally-proscribed, in addition to being actively hostile to internationalism, so I don’t know how much he’s going to care about convention here.
