Twenty-five Canadian students were released Wednesday from medical surveillance in northeast China's Jilin Province, local government sources said.

The overseas students at Northeast Normal University were put under observation at a hotel immediately after flying to Changchun, capital of Jilin, on May 2, from Canada via Beijing.

The students have displayed no influenza A/H1N1-like symptoms, including fever and sore throat, the Jilin Provincial Publicity Department said late Wednesday.

Foreign Ministry spokesman Ma Zhaoxu said Tuesday the quarantine was in line with Chinese Law to ensure public health as Canada had reported 51 confirmed human cases of A/H1N1 flu by May 2.

A hotel manager said the university had brought to the students sports and entertainment facilities, including balls and DVDs, to help them kill time.

The university has arranged for the Canadian students visits to a national forest park and the provincial museum of nature in Changchun Thursday.

A plane sent to fetch 98 Chinese citizens from Mexico arrived in Shanghai Wednesday afternoon and all on board have been put under observation.

China's Ministry of Health said Wednesday that passengers on the mainland who took the same flight last Thursday with the Mexican man later diagnosed with A/H1N1 flu in Hong Kong will be out of quarantine Thursday if they display no flu-like symptoms.

Vice Health Minister Zhang Mao warned that China faces a growing risk of the influenza A/H1N1 spreading into its mainland although new cases worldwide increase at slower rate.
