The United States is already Mexico's largest trading partner.

Once every 12 years there is a unique opportunity to reinforce the bonds between Mexico and the United States, when our presidential election cycles coincide.

In terms of the espionage, this is something I have talked to President Obama about. We don't want it to mar the relationship between Mexico and the United States. But it is unacceptable for a country to practice such espionage, especially if there is a good relationship with the other country.

I think a good relationship that Mexico could maintain with the United States and vice versa should be based on trust, on opening - openness and constant dialogue that would allow us essentially to define, share objectives and to work towards those so as to avoid activities which are not known to the other government.

The biggest trading partner of the United States is not West Germany or Japan, it's right here.

For decades, Japan has been a friend and reliable trading partner with the United States, and I anticipate that relationship will prosper.
