But a group of Chinese nationals who underwent testing to obtain medical certificates for overseas travel recorded positive results on Saturday, sparking fears of a wider outbreak in the community, reports AFP news agency.

"We have discovered a big community infection with 32 cases... this is a bad situation for us," Hun Sen said during a speech broadcast on state-run TV as quoted by AFP

"Those found positive today are all Chinese."

The increasing presence of Chinese businesses across the kingdom has heightened anti-Chinese sentiment among some Cambodians, and Hun Sen urged people not to discriminate against Chinese nationals because of the latest outbreak, the French news agency reported.

The virus which is believed to have originated from China has now spread across the globe.
