NASHVILLE (AP) — Tennessee is opening offices in four countries to help increase exports to key international markets.

Gov. Bill Haslam and Economic and Community Development Commissioner Bill Hagerty announced Monday that the state has opened Export Development Offices in Mexico, the United Kingdom, Germany and China.

The offices will help Tennessee businesses navigate the exporting process by offering business intelligence, market analysis, sales and marketing planning, identification of distribution partners and company matchmaking.

The state's Economic and Community Development Department says Tennessee's total export volume has more than tripled in the past decade.

More than 6,400 Tennessee businesses sold nearly $30 billion worth of products around the world in 2011.

In a statement, Haslam said it is imperative that Tennessee businesses take steps to access foreign markets.
