TAIPEI/BEIJING (Reuters) - Czech Senate speaker Milos Vystrcil will "pay a heavy price" for making an official trip to Taiwan, the Chinese government's top diplomat said on Monday, prompting Prague to complain though Vystrcil said he didn't seek confrontation.
Vystrcil arrived in Taipei on Sunday on a visit to promote business links with Taiwan, saying the Czech Republic would not bow to Beijing's objections. China considers Taiwan a breakaway province ineligible for state-to-state relations.
Speaking while in Germany, Chinese State Councillor Wang Yi said there would be retribution.
"The Chinese government and Chinese people won't take a laissez-faire attitude or sit idly by, and will make him pay a heavy price for his short-sighted behaviour and political opportunism," China's Foreign Ministry cited Wang as saying.
Wang said the Chinese government and people will not tolerate such "open provocation" by Vystrcil and the anti-China forces behind him, though gave no details of how exactly Beijing would react.
Czech Foreign Minister Tomas Petricek said that although the government did not support the trip, Wang's remarks were too strong and that he wanted an explanation.
"I expect that Chinese side will explain them to us. The trip has of course an impact on relations with China, but I think that this has crossed the line," Petricek told reporters, according to the CTK news agency.
Vystrcil said in a statement that Wang's comments were an interference in the Czech Republic's internal affairs.
"We are a free country seeking to have good relationships with all countries and I believe this will be the case in the future irrespective of the statement of the Minister. And let me repeat again – this visit is by no means meant to politically confront anyone," he said.
Taiwan Economics Minister Wang Mei-hua declined direct comment on China's attack on Vystrcil, but said the two had much in common.
"The Czech Republic and Taiwan are free and democratic countries which put great store on human rights. We have the same values as the Czechs," she told reporters, speaking before a joint business forum with Vystrcil.
He is due to meet Taiwan President Tsai Ing-wen later and will address Taiwan's parliament before leaving on Friday.
Czech President Milos Zeman has sought closer business and political ties with China since taking office in 2013, but his efforts have been hit by failed investment plans and Czech wavering about allowing China's Huawei Technologies to play a role in developing next-generation telecoms networks.
