China defended on Tuesday its quarantine of 25 Canadian students in Changchun, capital of northeastern Jilin Province, saying it was in accordance with law and the Canadians had assented to it.

The students began a seven-day quarantine period at a hotel on May 2 when they arrived, the same day that Canada confirmed 51 cases of A/H1N1 epidemic infection, said Foreign Ministry spokesman Ma Zhaoxu.

Canada has recorded up to 140 cases of A/H1N1 flu by Tuesday, the third-highest figure following Mexico and the United States.

Ma said the quarantine was in line with the Law on the Prevention and Treatment of Infectious Diseases and Frontier Health and Quarantine Law of China.

The students were being treated well, and the authorities had made favorable arrangements for their residence, food and health care.

None of the students showed any signs of illness and they were satisfied with the situation, said Ma.

The local government had informed the Canadian embassy in China of the quarantine on May 3, and the two countries had been in close contact regarding the virus, said Ma.
