The mayor of Arcadia, California, a heavily Chinese-American suburb of Los Angeles, has agreed to plead guilty to a federal charge of acting as a foreign agent of China, spreading propaganda on behalf of Beijing, U.S. officials said on Monday.

Within hours ?of the case being made public, Eileen Wang, 58, resigned from Arcadia¡¯s city council, along with the ?position of mayor ?she assumed in February on a rotating basis, according to the city manager¡¯s ?office.

She appeared briefly before a federal magistrate judge who instructed attorneys to agree to a date for a future hearing when Wang will formally enter her plea. Bond was set at $25,000. Monday¡¯s proceeding was conducted through a ?Mandarin interpreter.
