The NBA will work to develop a minor league system in the United States before looking to establish an overseas presence, Commissioner David Stern said yesterday.

"The way we now see the development of basketball around the world is encouraging," Stern said, "but the NBA must develop a minor league in our country first, either expanding our relationship with the CBA or perhaps consider starting a league of our own in the next year to 18 months."

Stern emphasized there is "no specific program" for expansion abroad. He spoke at a news conference before the semifinals of the McDonald's Championship, which he billed as "an unofficial global club championship."
