The mainland's Taiwan affairs authority on Tuesday strongly condemned the ruling Democratic Progressive Party of Taiwan on manipulating Hong Kong affairs for political gains.

The DPP administration and the "Taiwan independence" separatists made accusations and attacks on Hong Kong police's arrest of Jimmy Lai Chee-ying, Lee Chu-ming and other instigators of the Hong Kong protests.

Zhu Fenglian, a spokeswoman for the State Council Taiwan Affairs Office, said the arrest of offenders who are suspected of organizing and participating in unauthorized gatherings is legal, which embodies the rule of law principle that those who violate the law will be prosecuted.

"The DPP used it to create hype and called white black," Zhu said. "Its nature of 'Taiwan independence' was exposed again, by meddling in Hong Kong affairs, seeking political gains and attempting to split the country."

She warned the DPP to stop the political manipulation and said that any political attempt to realize "Taiwan independence" or split the country will not succeed.
