NEW YORK CITY-Martin Burger has been named co-chief executive officer of Silverstein Properties in a move that CEO and president Larry Silverstein says will allow the company to further “finance new development projects, acquire new properties and form new joint ventures around the globe.”

The move comes on the heels of several Silverstein deals outside the US—including a 2010 joint venture with Poland’s Kulczyk Real Estate Holding and a January 2011 joint venture with China Bridge Capital and state-owned Jiangbeizui Central Business District Investment and Development Co.

Burger, who most recently helped secure financing for Silverstein’s Four Seasons Resort Orlando, will lead Silverstein Properties’ development efforts in China. He joined the company in 2010, from Artisan Real Estate Ventures, where he was founder, president and CEO.

“Under Larry’s leadership over the past 55 years, Silverstein Properties has grown to become a pre-eminent real estate development organization with incredible brand recognition and unlimited possibilities,” Burger said in a prepared statement. “I am very excited to continue my work with Larry and our team as we use this platform to launch even bigger and more exciting projects throughout the world.”

Silverstein added that “Marty has worked closely with our entire management team to expand our business at home and overseas. Thanks in large part to his efforts, we now have projects underway in Florida, Eastern Europe and China. This is a very exciting time for our company and for me personally.”

Silverstein and World Trade Center Properties president Janno Lieber will continue to oversee the redevelopment of the World Trade Center.
