TOKYO (AP) _ The Yomiuri, Japan's largest newspaper, said Thursday it has signed an agreement with the Chicago Tribune to broaden its news coverage in the United States.

``With this tie-up, the Yomiuri Shimbun can introduce broader and deeper aspects of America to Japan,'' the Yomiuri quoted Shoichi Oikawa, its director and managing editor, as saying.

Oikawa signed the agreement at the Tribune's main office in Chicago on Tuesday.

The Yomiuri quoted Scott Smith, publisher of the Tribune, as saying that the agreement between the two newspapers would also deepen the overall Japan-U.S. relationship.

Under the agreement, the Yomiuri will also be allowed to publish news from more than 40 U.S. newspapers, including the Miami Herald.

The Yomiuri, founded in 1874, has a morning circulation of more than 10 million. It also has relationships with the Washington Post and the Los Angeles Times.

The Chicago Tribune is owned by Tribune Co., the second-largest newspaper conglomerate in the United States. Last year, Tribune Co. bought the Los Angles Times.
