Negotiators from the U.S. and Canada are hoping to reach a deal on the ongoing North American Free Trade Agreement (NAFTA) talks currently underway this week in Washington. According to Reuters, while delegates from both countries worked to advance the talks further on Thursday, several crucial items remain to be settled.

“We are making good progress,” said Canadian Foreign Minister Chrystia Freeland, Canada’s chief negotiator for the NAFTA talks while speaking to reporters on Thursday evening. The Foreign Minister described the trade meetings as “constructive and productive.”

One of the major issues still to be resolved is the question of dairy quotas. President Trump has stated before that Canada’s dairy quota, in essence, cripples U.S dairy farmer’s ability to export north.
