Canadian officials announced that negotiations with the United States to update the Columbia River Treaty are on hold — nearly a year after the two nations declared a tentative agreement — as the Trump administration conducts a “broad review of its international engagement.”

In a statement, British Columbia’s Ministry of Energy and Climate Solutions said that the yearslong effort to update the 60-year old treaty that governs water storage and hydropower operations is on an indefinite delay.

“The U.S. has paused negotiations with Canada on an amended Columbia River Treaty. The U.S. administration said it is conducting a broad review of its international engagement,” the statement reads.
