Southern Arizona merchants are hoping to entice more people to consider doing business with Mexico, which is Arizona's most important international trading partner.

Jim Kuliesh, president and CEO of the Alliance of Construction Trades, is working with the Metropolitan Tucson Convention and Visitors Bureau to put on the AzBIZCon Technology and Construction Expo on Friday and Saturday in Tucson.

He says it will deal with the commercial and residential construction industries and business technology as they relate to trade with Mexico.

Felipe Garcia, who oversees Mexico marketing for the convention and visitors bureau, says the economic exchange between Arizona and its neighbor south of the border is astronomical and reciprocal.

"Every year $1 billion is spent by Mexican nationals here in Pima County and Tucson," Garcia says.

"The largest employer in the state of Sonora - 12,000 employees - is a based out of Tucson. It's a local Tucson company, the Offshore Group owned by people from Mexico. There's great opportunities," Garcia adds.

AzBizCon will be Friday and Saturday from 10 a.m. to 7 p.m. at Casino Del Sol Resort, 5655 W. Valencia Road in Tucson.

Organizers hope it becomes an annual event that will grow and flourish along with trade and cooperation between Arizona and Mexico.
