OTTAWA -- The daughter of a missing Chinese human rights defender is pleading with the Vietnamese and Chinese governments to reveal her father's whereabouts and allow him to travel to Canada.

Dong Guangping, an activist who has previously spoken out against China鈥檚 attempts to erase the bloody outcome of the 1989 Tiananmen Square student protest, has 鈥渄isappeared,鈥 according to his daughter.

Dong, a 64-year-old activist, was arrested on Aug. 24 in the Vietnamese capital of Hanoi, where he had fled after being released from prison in China.

His daughter, Katherine Dong, is a Toronto university student and became a Canadian citizen this past summer. The 22-year-old student has not heard from her father for more than 80 days and fears he has been handed over to Chinese authorities.

"He didn鈥檛 want me to live in a country without human rights鈥eloves his family and he is a courageous survivor," Katherine said Thursday at a news conference in Ottawa.

"I want to hold on to hope, but I fear the worst."

Alongside her at the event were representatives of the Toronto Association for Democracy in China and the Federation for a Democratic China, as well as Alex Neve, former secretary general of Amnesty International Canada.

The association for democracy says Dong Guangping has been granted asylum in Canada, but Ottawa was not able to persuade Vietnamese officials to allow him to leave the country.

Dong had been hiding in Vietnam for 31 months while trying to make it to freedom.

According to Neve, the family has been told that Dong鈥檚 case has been raised by Prime Minister Justin Trudeau and Foreign Affairs Minister Melanie Joly in recent international meetings with leaders of Southeast Asia in Cambodia and at the G20 summit in Indonesia.

In a statement to CTV News, Global Affairs Canada says it is 鈥渄eeply worried about Mr. Dong鈥檚 safety and wellbeing and has been raising our concerns at the highest levels. Officials are working to ascertain his whereabouts, including through diplomatic engagement with both Vietnam and China.鈥

The tension between China and Canada played out in front of cameras during an interaction between the Prime Minister and Premier Xi Jinping, when the Chinese leader criticized Trudeau for allegedly 鈥渓eaking鈥 information about their discussions.

DETAINED FOR DISSENT

Dong's supporters say he was fired from his job as a police officer in China in 1999 because he signed a public letter related to the anniversary of the 1989 Tiananmen Square protests.

He was later imprisoned for three years on charges of "inciting subversion of state power."

鈥淒ong Guangping, like other courageous activists in China, has refused to let themselves be silent around Tiananmen. The Chinese government brutally represses any attempts, including those by relatives of students who were killed to hold ceremonies memorializing their deaths - let alone more forceful campaigns insisting that the truth be told,鈥 said Neve, who is now a senior fellow at the University of Ottawa.

THREE ATTEMPTS AT ESCAPE

Dong fled to Thailand in 2015 with his wife and daughter, who were resettled to Canada as refugees, but he couldn鈥檛 get out. Despite being designated as a refugee by the United Nations High Commissioner for Refugees, Thailand sent Dong back to China where he was imprisoned for another three-and-a-half years.

In 2019, Dong tried to escape again by swimming from China鈥檚 east coast to an island under the control of Taiwan.

His daughter, Katherine, says her father swam for 12 hours before 鈥渉e couldn鈥檛 bear it anymore鈥 and was rescued by a Chinese fishing trawler.

In January 2020, the human rights activist fled a third time, and successfully made it across the border to northern Vietnam. Katherine says while hiding in Hanoi, her father was moved from one safe house to another while the Canadian government worked behind the scenes to secure travel documents for him.

The Dong family was initially asked by Global Affairs Canada to stay silent to allow diplomats to negotiate his release. Despite the delicate balancing game, Neve said the family made the decision to speak publicly after it became clear that Canadian officials had not heard anything about Dong for weeks.

鈥淓very hour, every day, and every week that goes past without knowing where he is, without knowing anything about his fate means really the danger he faces will only deepen. Being silent won鈥檛 help,鈥 said Neve.

It鈥檚 unknown how many human rights activists with Canadian ties are imprisoned in China, but Dong鈥檚 detention parallels the case of Uyghur-Canadian Huseyin Celil.

While on an overseas trip visiting his wife鈥檚 family in Uzbekistan in March 2006, China asked the Uzbek government to arrest Celil and extradite him. Celil has been in prison now for more than 16 years.

Fearing a similar fate for her father, Katherine Dong and supporters delivered personal appeal letters Thursday to the Chinese and Vietnamese embassies in Ottawa.

She is asking the two governments to allow Canadian officials to visit her father immediately, and to let him come to Canada without any further delay.
