Lighthizer has praised the U.S. -Mexico deal as likely to reduce the $71 billion trade deficit with Mexico.
'That means the negotiations aren't over yet, ' he said.
Freeland had been scheduled to deliver Canada's address to the General Assembly on Saturday in NY, but Canada exchanged the slot with another country. "There are negotiations that are going as we speak, we hope they realize that this is a great deal for all three countries".
