I agree with your comment. As a personal example—using your “gateway” term as well—once this free trade agreement is implemented, I expect there will be more businesses from Canada travelling to Jordan to experiment with the area, to start to negotiate on business deals. I have personally witnessed a few occasions, having been in Amman, where I was accompanying some Canadian businesses and the embassy staff was able to introduce them to additional business offerings in the neighbouring countries.
Not only does this provide an opportunity for Canadian business to expand in Jordan, but instantly they have doors open to the surrounding regions.
