From a quick search it seems this was a Presidential Memorandum not an Executive Action.

“Executive orders are generally more formal, require publication in the Federal Register, and must cite the President's legal authority, while memoranda are less formal, may not be published, and do not always require a justification of authority.”

These sometimes get called executive orders, like some memos that trump has signed in the last few months were called executive orders by the news and online.

They are essentially the same though. Memos carry legal weight and can direct agencies to carry out specific actions.
