BEIJING — A correspondent for The New York Times was forced to leave mainland China on Monday after the authorities declined to issue him a visa for 2013 by year’s end.

Chris Buckley, a 45-year-old Australian who has worked as a correspondent in China since 2000, rejoined The Times in September after working for Reuters. The Times applied for Mr. Buckley to be accredited to replace a correspondent who was reassigned, but the authorities did not act before Dec. 31, despite numerous requests. That forced Mr. Buckley, his partner and their daughter to fly to Hong Kong on Monday.

Normally, requests to transfer visas are processed in a matter of weeks or a couple of months.

The Times is also waiting for its new Beijing bureau chief, Philip P. Pan, to be accredited. Mr. Pan applied in March, but his visa has not been processed.

The visa troubles come amid government pressure on the foreign news media over investigations into the finances of senior Chinese leaders, a delicate subject. Corruption is widely reported in China, but top leaders are considered off limits.
