The Fairfax County Economic Development Authority announced Monday that it is opening a new office in Boston to try to lure New England companies to the county.

The Boston office is the EDA’s eighth, including its headquarters in Tysons Corner. Its only other U.S. office is in Los Angeles. Globally, the EDA has representatives in Bangalore, London, Munich, Seoul and Tel Aviv, setting it apart from other economic development authorities in the region.

Besides promoting Fairfax County to companies around the world, the EDA offers site location and business development assistance. It is funded by county general fund dollars.

The Fairfax EDA chose Boston for a new office because of its similarities with Northern Virginia, said Gerald Gordon, the EDA’s president and CEO.

“With its concentration of IT companies, strong venture capital community, life-science initiatives and renowned academic institutions, the Boston area shares many economic similarities with the Fairfax-Washington area,” Gordon said in a statement. “We are opening a Boston office to show New England companies how they can benefit by expanding with a Fairfax County location.”

A Boston-based public relations firm, Rasky Baerlein Strategic Communications, will run the new office, an EDA statement said.

The EDA signed a one-year, $72,000 contract with Rasky Baerlein, with an option to extend up to three years.
