Yes. For any kind of free trade agreement that is negotiated, there is a process under the regional trade agreements at the WTO to review those trade agreements and determine if they meet the requirements that a trade agreement must meet in order to be considered a valid trade agreement by the WTO.
I will admit that this process is not necessarily as rigorous as it might be, but there is a review. Countries have an opportunity to ask questions about the free trade agreement, and it has to meet certain requirements, such as substantially covering all trade.
