The ministry has already directed its representative office in Canada to tell the airline that the change is unacceptable to the government and people of Taiwan, said MOFA spokesman Andrew Lee (李憲章).
The Chinese Civil Aviation Administration had sent a notice to 36 foreign airlines, including a number of U.S. carriers, on April 25, asking them to comply with Beijing's standards, according to the White House.
Chang believes Air Canada agreed to make the change because the airline is eager to have new routes to China.
Air Canada is now negotiating a joint venture with Air China 601111.SS which the Canadian carrier has previously said is expected to be completed in the spring.
In a rare statement issued by the White House May 5, the USA government slammed China's demand as "Orwellian nonsense" and said it deemed the request "Chinese political correctness".
As recently as last week, the airline's website entries for Taiwan did not mention China, according to checks made by Reuters, and it was not clear when the change was made.

United States clothes giant GAP said it was "extremely sorry" for selling a T-shirt with an "incomplete" map of China, after it was accused of being disrespectful to the country's territorial sovereignty. "We've learned that a Gap brand T-shirt sold in some overseas markets failed to reflect the correct map of China".
The White House has condemned China's efforts to control how US airlines refer to Taiwan, Hong Kong and Macau, saying the push to make them comply with Chinese standards is "Orwellian nonsense".
I can't imagine that, as a graphic designer for USA clothing giant Gap, you would have ever anticipated that part of your job would require officially apologising to the nation of China thanks to an worldwide upset you caused with one of your shitty shirt designs.
