BEIJING - The Democratic Progressive Party (DPP) authority's attempt to rely on external forces to seek "Taiwan independence" is doomed to fail, a Chinese mainland spokesperson said Friday.

Zhu Fenglian, a spokesperson for the Taiwan Affairs Office of the State Council, made the remarks in response to Slovenian Prime Minister's negative comments on Taiwan.

Zhu reiterated that there is only one China in the world and Taiwan is an inalienable part of China. 

"The one-China principle is a widely recognized norm of international relations and a common consensus of the international community," Zhu said.

Meanwhile, Zhu slammed separatists seeking "Taiwan independence," such as Joseph Wu, a DPP official, noting that they will eventually be held accountable for their words and actions.

In response to Wu's latest "Taiwan independence" statements at an online event organized by the so-called "Global Taiwan Institute," Zhu said the institute is nothing but a bogus organization financed and controlled by "Taiwan independence" elements to sell their separatist ideas under the guise of academic study.

Wu and his ilk are habitual liars swindling the international community, and their aim is to fool the public and collude with external anti-China forces, Zhu said.
