PRAGUE, July 7 (Xinhua) -- Several thousand protesters are expected to come to the Tuesday demonstration against a visit by U.S. Secretary of State Condoleezza Rice to Prague on Tuesday morning, activists Jan Tamas and Jan Majicek said on Monday.

    Rice will visit the Czech Republic to sign the Czech-U.S. treaty on the stationing of a U.S. radar base on Czech soil on Tuesday.

    Tamas said that No to Bases planned a rally at Prague's Wenceslas Square at 18:00 on Tuesday.

    The signing of the treaty by Rice and her Czech counterpart Karel Schwarzenberg did not mean the end of protests, Tamas and Majicek, the organizer of the No to Bases group, said.

    The group wanted to focus on the autumn regional and Senate elections, they said.

    "I have sent a request for a meeting with Rice to U.S. ambassador Richard Graber," Tamas said.

    "We'd like to meet her and pass our position to her. We'd like to tell her that roughly two-thirds of Czechs are against the stay of foreign troops on Czech soil," he added.

    The protesters would march from the Wenceslas Square across the Mustek and Malostranska streets to the U.S. embassy, the Czech news agency CTK said.

    The United States has planned to build a radar base in the Brdy military district, some 90 km southwest of the Czech capital Prague, along with an interceptor missile base in Poland.

    Russia is strongly opposed to the deployment of the system, saying the plan poses a threat to its strategic interests. Up to 70 percent of Czech citizens also reportedly oppose the project.
