BEIJING - China firmly opposes the India's move to form the so-called "Arunachal Pradesh" on China's Zangnan under India's illegal occupation, a foreign ministry spokesperson said Monday.

The China-India boundary has never been delimited and is divided into the eastern sector, the middle sector, the western sector, and Sikkim section, spokesperson Lin Jian said in response to a relevant question at a daily news briefing.

Zangnan in the eastern sector has always been China's territory, Lin said.

"China had all along exercised effective administrative jurisdiction over Zangnan until India's illegal occupation. This is a basic fact that cannot be denied," said Lin.

Lin said in 1987, India formed the so-called "Arunachal Pradesh" on China's territory under India's illegal occupation. China issued a statement right then to firmly oppose it and stress that India's move was illegal and null and void.

"China's position remains unchanged," he said.
