Hong Kong's leader said Tuesday that her administration was determined to push through an extradition bill that could see individuals sent back to mainland China for trial, despite mounting opposition locally and internationally.

The proposed legislation has stoked mass protests in the former British colony, which was promised a high degree of autonomy under a "one country, two systems" formula when it returned to Chinese rule in 1997.

On Monday, the government said it would bypass legislative procedure to expedite the passage of amendments to the Fugitive Offenders Ordinance, which the U.S. State Department last week described as threatening the rule of law in Hong Kong.
