A foreign ministry official said on Tuesday that China is studying human biological identification technology to strengthen entry/exit management.
Cui Aimin, an official with the Ministry of Foreign Affairs, made the remarks while taking questions from reporters at a press briefing.
China's top legislature reformed exit and entry law in July 2012, introducing a common international practice by which immigration authorities may collect fingerprints and other biodata from those who exit or enter China's territory.
The number of foreigners entering China has been increasing by 10 percent annually since 2000, according to the Ministry of Public Security.
China's police organs have collected immigrant's finger prints since 2005 to improve efficiency of immigration procedures and protect national security.
