Police detained four murder suspects in Zhuhai on Sunday and Monday after one Taiwan resident was found dead and another injured in a hotel on Saturday.
They say they are still hunting three other suspects following an attack that is believed to have been the result of a dispute over counterfeit money.
The four were seized in the Zhuhai Special Economic Zone in the southern province of Guangdong, bordering Macao Special Administrative Region.
The dead man and the injured victim, who is still receiving medical treatment, were employees of the Taiwan-based Far Eastern Air Transport Co Ltd.
A senior police officer from the provincial Public Security Bureau said the case would be investigated to its "fullest extent."
Officers were called to the hotel in the Jida District of Zhuhai at 5:50 AM last Saturday and found the two men seriously wounded in their room.
One, in his 30s, died at the scene and the other, 48, was rushed to hospital for emergency treatment, a police officer told China Daily Wednesday.
