Most of the foreign airlines that agreed to tweak references to Taiwan to reflect the island as part of mainland China have been given more time to comply as Beijing extends a crackdown on companies regarding its stance on disputed territories.

Air France-KLM and Deutsche Lufthansa AG are among airlines that have made changes to their websites, while those that have received or applied for an extension include Japan Airlines Co. and ANA Holdings Inc. as well as United Continental Holdings Inc. from the United States.

The Civil Aviation Administration of China said late Friday that all 44 carriers that were asked to modify their Taiwan references will do so. Eighteen made the required changes before a May 25 deadline, and the rest asked for extensions and were given until as late as July 25 to comply, the regulator said.
