The United States women's volleyball team, ranked second in the world, hopes to continue its success against top-ranked China tonight at George Washington University's Smith Center at 7:30.

The teams have met four times on a current U.S.-China national tour, with the Americans winning three matches, including two by sweeping three straight games in best-of-five competition. The tour continues at Rutgers, before finishing in Stockton, Calif. The teams will play seven matches.

China attained its ranking on the basis of its victory in the World Cup events in Tokyo last November and is one of the teams the U.S. will have to beat to win the world championship in Peru in September, or an Olympic medal in the 1984 Los Angeles Games.

China defeated the Americans in a grueling five-game match during the World Cup, an event in which the U.S. finished fourth. During the World Cup, the U.S. defeated the Japanese, who finished second, in five games. On the final night, the Americans lost to the Soviet Union in three straight games, enabling the Soviets to finish third.

The fourth-place finish, however, is the highest ever by the American women in a legitimate major international championship. The U.S. finished second to Japan in the 1967 World Championship, but that tournament was boycotted by the Communist nations.

Since 1980, the U.S. has defeated every major international power. The Americans, coached by Arie Selinger, are very aggressive on offense, led by 6-foot-5 hitter/blocker Flo Hyman of Inglewood, Calif.

Hyman was selected as the most valuable offensive player of the championship at the World Cup Tournament.

Tickets are on sale at Smith Center, at $7 and $5 for students.
