A Chinese mainland spokesperson said Saturday that Taiwan's attempts to mess up Hong Kong will only backfire. 

Ma Xiaoguang, spokesperson for the Taiwan Affairs Office of the State Council, said the decision of the National People's Congress on the national security legislation for the Hong Kong Special Administrative Region (HKSAR) targets a very narrow category of acts that seriously jeopardize China's national security.

"It aims to protect the rights and freedoms of Hong Kong residents and provide a fundamental guarantee for the effective implementation of 'One Country, Two Systems,'" he stressed.

Taiwan's Democratic Progressive Party (DPP) has been distorting the facts and constantly attacking and slandering NPC's Hong Kong-related decision, because the legislation aims to eradicate the forces advocating "Taiwan independence" and "Hong Kong independence," said Ma.

He said Taiwan's so-called "rescue operation" offers a blatant way out for Kong Kong rioters and further exposes DPP's vicious motives of political manipulation in Hong Kong affairs, its attack on the "One Country, Two Systems" principle and quest for "Taiwan independence," said Ma, adding that Taiwan's conspiracy will not succeed.
