China had slammed India's move as "self-deception" that could complicate border issues.
"China does not recognize the so-called 'Arunachal Pradesh' illegally set up by India," Chinese Foreign Ministry spokesperson Jiakun said.
"Still less will it change the fact that Zangnan region belongs to China," he said.
China calls Arunachal Zangnan.
The Global Times reported Qian Feng, director of the Research Department at Tsinghua University's National Strategy Institute, as saying such actions could stifle improving political ties between China and India.
