Nigeria MPs have asked the government to investigate the status of Chinese residents in the country, saying some may be staying there illegally.
The demand follows allegations that Nigerians in China, especially those in jail, are being mistreated.
The MPs asked the government to reject a request by the Chinese authorities to cremate the bodies of 30 Nigerians who have died in Chinese jails.
There are an estimated 700 Nigerians currently in prison in China.
The BBC’s Chris Ewokor in Abuja says they are mainly charged with immigration, drug or fraud offences.
