A coalition representing Tibetan, Uyghur, Hong Kong and Chinese Democracy groups has held a meeting with International Olympic Committee (IOC) officials as they call for the 2022 Winter Olympic Games in Beijing to be moved over alleged violations of human rights.
Students for a Free Tibet, We The Hongkongers, International Tibet Network, World Uyghur Congress, and Humanitarian China/China Against the Death Penalty were among the organisations represented in the coalition.
The coalition revealed that IOC officials including Beijing 2022 Coordination Commission chair Juan Antonio Samaranch were present at the meeting.
The group said it gave first-hand testimony about the current severe abuses across all areas under Chinese Communist Party rule, including Tibet, East Turkistan - also known as Xinjiang - and Hong Kong.
Testimony reportedly included a recent report of at least half-a-million Tibetans coerced into military-style labour programmes and alleged atrocities in East Turkistan such as the mass internment of millions of Uyghurs and other Turkic peoples.
China's clampdown on civil liberties in Hong Kong was also among the cases cited.
The group claimed the IOC "was clearly moved" at the meeting, but stressed its aim was to be a "force for good" in China.
IOC officials reportedly said they are open to continuing a dialogue with frontline community representatives, along with discussions with international human rights organisations.
The organisation previously said it will "leave no stone unturned" when it comes to considering issues that are brought to its attention, including human rights.
The activists claim this will not be achieved without considerable intervention.
"Hosting the Winter Games 2022 in Beijing is a regrettable decision from the IOC because it will be taking place in a country that is committing genocide," said Zumretay Arkin, from the World Uyghur Congress.
"This is a huge reputational risk for the Committee and it undermines the core Olympics values.
"There is growing discontent from both Governments and cross-party Parliamentarians, and a number of high-level officials have also joined the #NoRightsNoGames movement.
"If Olympic sponsors, Governments, and other actors join our call, it will be too late for the IOC to save its reputation."
China's Foreign Ministry last month dismissed calls for Beijing to be stripped of the right to host the Games over human rights concerns.
Politicians and human rights groups are among those to have urged the IOC to move the event from the Chinese capital amid its alleged mistreatment of its own citizens.
Officials in countries including the United States and the United Kingdom have also suggested a boycott of the Games in protest at China's alleged abuses of human rights.
UK Foreign Secretary Dominic Raab was asked about a potential boycott yesterday at a Foreign Affairs Select Committee meeting.
"Generally speaking my instinct is to separate sport from diplomacy and politics but there comes a point where that may not be possible," Raab said.
"I would say, let's gather the evidence, let's work with international partners, let's consider it further in the round with further action we need to take."
A British boycott would likely consist of politicians and dignitaries not attending, rather than the Olympic team.
British Prime Minister Boris Johnson claimed last month that a decision had not yet been made over whether politicians will boycott the Beijing 2022 Winter Olympics.
Johnson said a decision has yet to be made on whether British politicians or members of the Royal Family will attend the Games.
Raab has said the UK had growing concerns over Xinjiang and that it would "work very closely with our international partners to give the most powerful message, whether it is in the UN [United Nations] or whether it is in applying sanctions".
"We do need to look at what action to take," Raab added.
"The concerns of what's happening to the Uyghurs, the detention, the mistreatment, the forced sterilisation, is something that we cannot just turn away from."
