China is objecting to a decision by Internet search engine Google to change maps referring to Taiwan as a province of China.
China's state media report that officials are worried the decision may mislead people and give the impression of an independent Taiwan.
A Google spokesman told Xinhua the change was part of a regular update of all the site's maps, rather than a deliberate effort to update the Taiwan page.
Earlier this month, Taiwan asked Google to stop listing it as a Chinese province on its maps. Now Google maps simply call the island Taiwan.
Taiwan calls itself the Republic of China. China views Taiwan as a breakaway province. The two split in a civil war that ended in 1949.
