to have materially assisted, sponsored, or provided financial, material, or technological support for, or goods or services in support of, any activity described in subsections (a)(i) or (a)(ii)(A)
According to the EO, you only need to "provide technological support." And what does that entail? Whatever the Secretary of Treasury and AG decide it does.
Once again: the EO can only do what the IEEPA allows it to do. It does not matter what the EO says: if it conflicts with (or, in this case, is simply vague about) something in the IEEPA, it's the IEEPA that controls. Look at your own citation (50 USC 1702 is part of IEEPA); it's right there in the text.
This has come up before in US law --- executive orders w/r/t IEEPA --- before, by the way.
