MANILA — Philippine President Benigno Aquino III canceled a trip to a Chinese trade fair after Beijing demanded that he first withdraw a legal complaint over disputed territories in the South China Sea, Filipino officials said Monday. Chinese Foreign Minister Wang Yi and two other diplomats relayed conditions for Aquino to attend the annual China-ASEAN Expo, which opens Tuesday in the southern city of Nanning, Department of Foreign Affairs spokesman Raul Hernandez told a news conference. Hernandez declined to detail the conditions, but said these were “absolutely inimical to our national interest.” The Chinese side asked that the conditions not be publicly disclosed, he said. They were discussed by Wang and Philippine Foreign Secretary Albert del Rosario in Beijing on Wednesday. Because of the conditions, Aquino decided to call off his publicly announced trip to the trade fair, Hernandez said, adding the Philippines will instead send a delegation headed by its trade secretary. “The president stood firm in the defense of the country's wnational interest,” Hernandez said. Two Philippine officials told the Associated Press that China wanted Manila to withdraw a UN arbitration case over disputed islands in the South China Sea. The officials spoke on condition of anonymity because they were not authorized to speak to reporters. China was concerned that allowing Aquino to visit after the Philippines brought its territorial disputes to UN arbitration in January — which Beijing calls an “unfriendly act” — may not be welcomed by the Chinese public and media, the officials said. Asked to comment Monday, Chinese Embassy spokesman Zhang Hua did not react to their statements, but urged the Philippines to work with China “to overcome difficulties and disturbances and make real efforts to get the China-Philippine relationship” back on track. — AP
