Acting under pressure from Taiwan, the Japanese organizers of an exhibition of ancient Chinese artifacts on loan from the Taiwan National Palace Museum said Sunday that they have taken steps to remove promotional materials that dropped the word "national" in referring to the government-operated institution.

Officials of the Tokyo National Museum said they hope to hold the opening ceremony for the special exhibition on Monday as scheduled, if approved by the Taiwan National Palace Museum.

The controversy surfaced Friday after the Taiwan Presidential Office issued a statement of protest, warning that the exhibition would be canceled unless organizers in Japan took steps to call the Taiwan museum by its official name.
