When the United States withdrew from the Trans-Pacific Partnership shortly after President Donald Trump took office last year, it was unclear what would happen next. Would the remaining 11 countries renegotiate or abandon the deal altogether?

Britain’s vote in June to leave the European Union (EU) carries with it a mass of unknowns. In fact, the only certain thing about the outcome is continued uncertainty.

Before the Trans-Pacific Partnership (TPP), U.S. cheese exporters faced a 245% out-of-quota tariff if they wanted to ship to Canada. After TPP is implemented, U.S. cheese exporters will continue to face a 245% out-of-quota tariff, but with the opportunity to compete for a larger quota of various cheeses.
