CHINA will study proposals by Hongkong delegates to the National People's Congress and the Chinese People's Political Consultative Conference to strengthen their participation in transitional affairs in the run up to 1997. Hongkong NPC deputy Miss Liu Yiu-chu has urged the local branch of the New China News Agency to help Hongkong NPC deputies set up a working group to oversee preparatory work for the establishment of the Special Administrative Region government. A newly-reappointed CPPCC member, Mr Lau Nai-keung, has also proposed that the CPPCC Secretariat set up an office in Hongkong so local delegates can better organise themselves and play a greater role. Miss Liu's proposal was put to Mr Wang Rudeng, a NCNA assistant director and head of the Hongkong delegation to the Guangdong Provincial People's Congress, when the congress convened late last month. Miss Liu has invited all the other 27 Hongkong NPC deputies, including NCNA director Mr Zhou Nan, to a meeting on March 7 to discuss her proposal to organise a ''Hongkong NPC small group''. According to a new law on NPC deputies passed last year, the NPC deputies at various levels are authorised to organise themselves into ''small groups'' to oversee specific issues that fall within the jurisdiction of the NPC when the NPC is not in session. In response to Miss Liu's proposal, Mr Wang Rudeng said the NCNA supported the efforts of local NPC deputies to play a larger role in transitional matters, but added the NCNA needed more time to study the plan.
