The disrespect toward Sihanouk, who died here last week, from the "relevant person" was extremely wrong and the case should be dealt with by the Cambodian side, Chinese Foreign Ministry spokesman Hong Lei told reporters.
Hong said that the former king was China's great friend and loved by Cambodians.
Yesterday, the woman supervisor with a Chinese garment factory in Cambodia tore a poster of the late King because she alleged that the workers were working at a slow pace.
More than 1,000 irate workers resorted to protest asserting she had insulted their former King, whose body was lying in state for people to pay homage.
The Chinese supervisor was subsequently arrested and is expected to face trial.
