"TECC is deeply disappointed with Air India changing "Taiwan" into "Chinese Taipei" on its website and regrets that this move taken by Air India, a state-owned airline, can be seen as a gesture of succumbing to the unreasonable and absurd pressure from China", said Ambassador Chung in a press release.

The Chinese Civil Aviation Administration on April 25 sent a letter to 44 global airlines requesting that they change references to Taiwan, Hong Kong and Macau on their Web sites and in other company materials within 30 days, or suffer repercussions for "serious discreditable conduct". However, the Modi government used to be proud of declaring that they had told off China on India's "one-China" policy, by saying they would support it only when China supported a "one-India" policy. China has claimed sovereignty over Taiwan since the end of the Chinese civil war in 1949, when the defeated Nationalist government fled to the island.
The United States and Australia have also slammed China's pressure on companies. China has requested that many influential companies from around the world such as Mercedes-Benz, Zara, Marriott, and GAP identify Taiwan, Tibet, Hong Kong, and Macau as part of China.
