Beijing, China - China warned outspoken Hong Kong Bishop Joseph Zen on Thursday not to mix politics and religion, after Pope Benedict XVI named him a cardinal.
Chinese foreign ministry spokesman Liu Jianchao also said Beijing's position on refraining from establishing diplomatic ties with Rome had not changed because of the appointment.
"We have taken note that Joseph Zen was appointed as a cardinal by the Vatican," Liu told journalists at a routine briefing.
"We advocate that religious figures should not interfere with politics."
Liu also expressed hopes that the appointment would not disrupt social stability in Hong Kong.
"We hope that all communities in Hong Kong can maintain social stability and the harmony and devlopment of Hong Kong," he said.
The outspoken Zen, who on Wednesday became the sixth Chinese in history to be named a cardinal, said on Thursday he hoped his appointment could help end the 55-year dispute between the Vatican and China.
Zen has long been a fierce critic of the Chinese government and has often joined in pro-democracy protests in the territory.
The Chinese government has repeatedly said it is willing to improve relations with the Vatican only if it breaks off ties with Taiwan, which Beijing regards as a renegade province.
Another condition imposed by Beijing is for the Vatican not to interfere in China's internal affairs, in reference to how the government controls religion.
"We have repeated our position on relations with the Vatican many times," Liu said.
"There is no change in our position."
Liu refused to comment on whether Zen's appointment would help China in eventually normalising relations with the Vatican.
