Global Affairs Canada published a joint statement in which 10 foreign ministries said Joshua Wong was sentenced to 10 years in prison on a further charge under Hong Kong’s National Security Law.

The ministries called the case another instance of that law being used against people for political expression and participation. They asked for an immediate end to prosecutions they called unjust, and they urged authorities in China and Hong Kong to meet international commitments.

Australia, Canada, France, Germany, Italy, Japan, the Netherlands, New Zealand, the United Kingdom and the United States issued the statement together. Global Affairs Canada posted the same wording twice on its site: once as its own statement and once as the joint text from the 10 foreign ministries. The posting did not name a person as the signer.

Wong was sentenced to 10 years’ imprisonment after a further charge under the security law, the ministries said. They did not say when a court imposed the sentence, what the further charge alleged, or where he would serve the term.

They also said leaders of the Hong Kong Alliance had been convicted under the same legislation only months earlier. The statement did not name those leaders, say how many people were convicted, or describe the sentences in those cases.

The ministries said the Wong sentence and those convictions are further examples of the security law “being used to target individuals for political expression and participation.”

The group called for “an immediate end to all unjust prosecutions” of people charged under the law. It urged officials in China and Hong Kong to uphold their international commitments and to honour the rights and freedoms that, the ministries said, the Sino-British Joint Declaration of 1984 guarantees to the people of Hong Kong.

The ministries did not describe other terms of that 1984 declaration. They also did not say what the 10 governments would do if the prosecutions continue, or whether the authorities in China or Hong Kong had replied. The Canadian page listed a media office for Global Affairs Canada but did not add further details about the case.
