"The biggest challenge for keeping ties productive will be sustaining the attention necessary to tackle deep-rooted problems," writes AS/COA's Carin Zissis in World Politics Review.

After five years and a nearly 20-month border shutdown, the heads of government of Mexico, Canada and the United States gave a sense of restored normalcy to trilateral relations last month, when they joined up in Washington for the first summit of its kind since a 2016 gathering—featuring a famously awkward handshake—in Ottawa.
