BEIJING (BLOOMBERG) - Nasa has become the latest foreign organisation to upset China by referring to Taiwan as a country, the latest in a string of quarrels the Asian nation has waded into over wording it deems politically sensitive.
The United States space agency has hurt the feelings of the Asian country's 1.4 billion people with the reference on its website, said Ms Zhu Fenglian, a spokesman for the Beijing office that handles matters related to the democratically ruled island.
The space agency needs to "correct its mistake as soon as possible", Ms Zhu said at a regular press briefing on Wednesday (March 31) in Beijing.
A commentary published by People.cn on Monday described the incident as "unforgivable".
The website is run by the People's Daily, the Communist Party mouthpiece.

Taiwan appears as an option on a "country" drop-down box, as does the Vatican.
It is unclear how long Taiwan has been called a country on the website, but more than 18 million people have registered.
An e-mailed request for comment sent to Nasa outside regular business hours was not immediately answered.
