WASHINGTON, July 1 (Xinhua) -- The United States said on Tuesday it will reach an agreement soon with Poland on setting up a missile defense base in the eastern European country.

　　"We've had these conversations for a long time, and I think you'd see a resolution of this somewhere in the coming days," State Department deputy spokesman Tom Casey told reporters here.

　　"But whether that's in a week or two weeks, I'm not really in aposition to say. It will all depend on the pace and structure of the negotiations," he said.

　　The United States, planning to deploy 10 missile interceptors in Poland and a radar system in the Czech Republic as part of its European missile shield, started negotiations with Poland on the missile shield issue in 2002. But the two countries have failed to make any significant progress in the past several years.
