WASHINGTON – Today during the Senate Finance Committee’s hearing on President Donald J. Trump’s trade policy agenda with United States Trade Representative (USTR) Ambassador Jamieson Greer, U.S. Senator John Cornyn (R-TX) urged the Trump administration to push Mexico to comply with the 1944 Water Treaty through the United States-Mexico-Canada Agreement (USMCA) joint review process. Excerpts of Sen. Cornyn’s remarks are below, and video can be found here . CORNYN: “On July the first, the U.S. formally declined to renew the USMCA during the joint review. Yet, as you know, it remains in effect essentially with an annual review process. But what are we to make of the administration’s decision to [decline] to renew the USMCA?” GREER: “The options are, you can rubber stamp the agreement and renew it without further revisions, or you can enter into this period where we decline to renew and see if there are ways to improve the trading relationship, and so you should look at it in the latter way.” “We want to make sure that any beneficial trade between our countries benefits our countries and not a third country like Vietnam or China.” “Mexico has consistently not lived up to its obligations under the 1944 Water Treaty with the United States… Is there any way that the joint review process can reinforce those compliance and accountability for Mexico to help safeguard our farmers in South Texas?” GREER: “It is clear, from President Trump’s perspective, that if we want to have a beneficial trading relationship with Mexico and have some kind of arrangement with them, they also need to be playing ball on this issue.” “The President is going to have a hard time agreeing to renewal or even revisions, if Mexico isn’t playing ball in all areas, and the water treaty is one of them.”
