BEIJING has committed itself to seeking peaceful reunification with Taiwan while failing to make a formal commitment to dropping the ''military option'' against the Kuomintang stronghold. But the head of China's quasi-official Association for Relations Across the Taiwan Strait, Mr Wang Daohan, has hinted Beijing might consider declaring an end to hostility between both sides. During a meeting in Beijing yesterday between Mr Wang and the visiting vice-chairman of Taiwan's quasi-official Straits Exchange Foundation (SEF), Mr Cheyne Chiu, it was also disclosed that Mr Wang had already had direct contacts with SEF chief Mr Koo Chen-fu in the United States and Japan. While bidding farewell to Mr Chiu at the Great Hall of the People, Mr Wang said the mainland wanted to use peaceful ways to achieve reunification. ''Both sides need to sit down and talk to increase understanding and to find out ways with which both sides agree,'' he said. ''The mainland will take care of the interests of compatriots in Taiwan, but it must also consider the interests of the entire Chinese race.'' Mr Wang, a former mayor of Shanghai who is considered close to party General Secretary Mr Jiang Zemin, also said it was acceptable that talks began with administrative and procedural matters. Mr Chiu, who returned to Taiwan last night, reiterated Taipei's stance that under its mainland policy, relations with Beijing were only at the first stage of indirect, people-to-people ties. The Independent Morning Post of Taipei yesterday quoted Mr Wang as saying ''relevant units'' in Beijing were studying the possibility of declaring an end to hostility between the mainland and Taiwan. ''The units are doing research on an adequate way, which is agreeable to both sides, to declare to the world that both sides have ceased their state of hostility,'' Mr Wang was quoted as saying. There has been intense speculation in Taipei that a secret item on the agenda of the Koo-Wang summit to be held in Singapore later this month, concerns a non-aggression agreement between Taipei and Beijing. Political analysts said Beijing had ruled out a formal non-aggression pact because this entailed the existence of two equal political entities. But Mr Wang's hint about the declaration of an end to hostilities came close to a renunciation of the military option against Taiwan. The analysts also said it was noteworthy that Mr Wang did not specify yesterday the format of bilateral talks. Formerly, Beijing had insisted that all interchanges should be made between the Communist Party and the Kuomintang. Meanwhile, it was disclosed in Beijing yesterday that Mr Wang had already met Mr Koo, a former Central Standing Committee member of the Kuomintang, on two occasions in San Francisco and Osaka. It is believed emissaries or proteges of President Mr Lee Teng-hui have had meetings with senior Beijing cadres in recent months.
