HUMAN rights remains a main concern for the US Government as it decides whether to renew China's most-favoured nation (MFN) trading status, according to Secretary for Trade and Industry Chau Tak-hay after his lobbying mission in Washington. . ''In so far as President Bill Clinton's executive order does include conditions relating to various aspects of human rights, I would say that [this] is certainly one of the considerations which the Clinton administration will take into account when deciding [whether] to allow MFN this year,'' said Mr Chau, who returned from Washington on Saturday. Describing the visit as successful, he said his main lobbying position had been putting forward Hong Kong's argument for renewing China's trade privileges for the coming year. Mr Chau lined up a series of top officials and congressmen to try to rescue China's case, following the disastrous visit of Secretary of State Warren Christopher to Beijing. Despite meetings with top officials such as Trade Representative Mickey Kantor and influential congressman Sam Gibbons of the House Ways and Means Committee, Mr Chau said he did not get any hints on the Government's position on the MFN issue. ''The general impression that I received both from members of the US Government and members of the Congress [is that] they are still trying to digest the developments which occurred during [Mr] Christopher's visit.''
