HONG KONG - An ongoing signature campaign for the support of universal suffrage of chief executive in 2017 in Hong Kong Special Administrative Region has collected 363,487 names so far, according to the campaign's website on Monday.

Organized by the Alliance for Peace and Democracy, the campaign aims at gathering Hong Kong people's support for the constitutional reform package designed for the election of the next chief executive by "one person, one vote" universal suffrage.

The package was unveiled by the Hong Kong government on April 22.

Among the signers were top government officials including Chief Secretary for Administration Carrie Lam and Secretary for Constitutional and Mainland Affairs Raymond Tam.

Lam said on Sunday that Hong Kong's constitutional reform is at its most critical moment and the government is working hard to garner more public support for the reform package in the coming weeks, stressing that the reform package is a comprehensive and legally practical one.

The region-wide signature campaign was launched on Saturday and will last until May 17.
