Lawmakers have urged the government to address the trend of holding dual nationality, which is illegal in China.

Jin Shuoren, a member of the National People's Congress Standing Committee, said on Thursday that although being a citizen of two or even more countries at the same time is not allowed in China, it has become an increasingly popular practice and the government needs to take more action to deal with it.

"The government should set up a system holding nationality information by compiling data from different agencies to compare and find out about holders of dual nationality," he said.
