Democratic Party lawmaker Fred Li Wah-ming is among the few moderate democrats invited to the central government liaison office spring reception. Others who have confirmed receiving invitations include accountancy representative Mandy Tam Heung-man and Kwok Ka-ki, who represents the medical sector. Mr Li said he was happy to receive the invitation. He was first invited by the liaison office in 2000, along with former lawmakers Tik Chi-yuen and Yuen Long District Council member Zachary Wong Wai-yin. He is so far the only Democratic Party member invited to the annual gathering, being held at the Hong Kong Convention and Exhibition Centre on February 22. Gao Siren, director of the liaison office, will attend the reception, long viewed as a litmus test of how the central government is willing to improve relations with the pro-democracy camp. Mr Li said: 'Maybe because I don't have a home-return permit, I can only participate in activities [organised by Beijing] in Hong Kong.' Most hardcore Democrats are barred from the mainland or have had their home-return permits revoked.
