China on Friday threatened "counter-measures" against Sweden if the culture minister awards a Swedish PEN rights prize as planned to detained Chinese-Swedish book publisher Gui Minhai.
"China resolutely opposes Swedish PEN awarding a criminal and lie-fabricator... We oppose even more resolutely any Swedish government officials attending the award ceremony," China's ambassador to Sweden Gui Congyou said in remarks published in English on the embassy website.
"We will surely take counter-measures," he said. "Some people in Sweden shouldn't expect to feel at ease after hurting the feelings of the Chinese people and the interests of the Chinese side.
"Normal exchanges and cooperation will be seriously hindered," he said.
Swedish Prime Minister Stefan Lofven said the Scandinavian country would not back down.
"We are not going to give in to this type of threat. Never. We have freedom of expression in Sweden and that's how it is, period," he told Swedish Television.
Culture and Democracy Minister Amanda Lind was due to present Swedish PEN's Tucholsky Prize to Gui Minhai at a ceremony on Friday evening in Stockholm.
Currently in detention at an unknown location in China, he will be represented by an empty chair on the stage.
Lind termed Beijing's threat as "serious".
"We have made it clear to China's representatives that we stand by our position that Gui Minhai must be released and that we have freedom of expression in Sweden," Lind told Swedish news agency TT.
"This means that Swedish PEN must of course be allowed to award this prize to whoever they want, free of any influence. And as Culture and Democracy Minister it is natural for me to attend the award ceremony," she said.
The annual Tucholsky Prize, worth 150,000 kronor (14,000 euros, $15,500), is awarded to a writer or publisher being persecuted, threatened or in exile from his or her country.
Strained Ties
Relations between Sweden and China have been strained for several years over Minhai's detention.
A Chinese-born Swedish citizen known for publishing gossipy titles about Chinese political leaders out of a Hong Kong book shop, Gui Minhai, 55, disappeared while vacationing in Thailand in 2015 before resurfacing in mainland China several months later.
He appeared on Chinese state television confessing to a fatal drink driving accident from more than a decade earlier.
He served two years in prison, but three months after his October 2017 release he was again arrested while on a train to Beijing, travelling with Swedish diplomats.
His supporters and family have claimed his detention is part of a political repression campaign orchestrated by Chinese authorities.
The Chinese ambassador said Gui Minhai had "spread lies and viciously attacked the Chinese government", adding that Beijing supported "freedom of expression based on objective facts, not 'freedom of lies'."
The Tucholsky Prize is named after German writer Kurt Tucholsky, who came to Sweden in the early 1930s as a refugee from Nazi Germany.
The prize, established in 1984, has been won by Adam Zagajevski, Nuruddin Farah, Salman Rushdie, Taslima Nasrin and Svetlana Alexievich, among others.
