China-Kazakhstan to share migration data, closing route for some, including from Xinjiang, keen to bypass Beijing

A new bill recently passed by Kazakhstan to allow Astana and Beijing to share immigration information would effectively close an immigration pathway for some Chinese nationals, including people from Xinjiang, who have bypassed Chinese authorities to relocate to Kazakhstan, experts say.

The bill comes after years of efforts by Astana to crack down on dual citizenship, and would be the last legal step before a visa-free regime between the two nations comes into effect. Dual citizenship is illegal in both China and Kazakhstan.

The law, which ratifies an agreement originally signed by ministers in May during a visit by President Kassym-Jomart Tokayev to China, was passed in the Senate last week. The bill was passed in the lower house in September, and awaits the president's signature.

The agreement authorises China and Kazakhstan to exchange information on citizens - including their name, date and place of birth, photograph, identification issuing authority and citizenship status - according to the agreement posted online for comment in early May.

The two countries will also share citizens' entry and exit records, and whether a person had terminated their citizenship in one country when they became a citizen of another, according to the draft agreement.

Maulen Ashimbayev, chair of the senate, said during the senate session that the agreement was necessary for the "fight against dual citizenship".

The deputy minister of internal affairs, Igor Lepekha, said during the senate session that China required the agreement on exchanging citizen information to be passed as a provision for allowing a visa-free regime between the two nations, according to Kazakhstan-based news agency Zakon.

Beijing agreed during President Tokayev's visit in May to issue a visa-free policy to Kazakhstan citizens with the information exchange agreement as a condition. The visa-free regime makes Kazakhstan the third country - along with Singapore and Brunei - whose citizens can travel to China without a visa. Chinese citizens have been able to travel to Kazakhstan freely since last year.

"The Chinese side understands that if visa-free travel starts now, the flow of citizens from one side and the other will increase. And in order to primarily control illegal migration, ratification of this agreement is required," Lepekha said.

Kazakhstan has signed similar agreements to avoid dual citizenship with five other nations: Azerbaijan, Belarus, Kyrgyzstan, Tajikistan and Uzbekistan.

The bill will effectively end a decades-old loophole through which Chinese nationals, mostly from Xinjiang Uygur autonomous region, have circumvented Chinese authorities to become citizens of Kazakhstan.
