Officials in Beijing demanded an apology from France's AFP news agency, saying it had mislabelled a picture of weapons displayed in an exhibition on Tibet, according to a long article by the Chinese communist party mouthpiece, Xinhua news agency late on Friday.
The French news agency had already corrected the caption.
Relations between China and France have been testy since French President Nicolas Sarkozy met the Tibetan Buddhist leader, the Dalai Lama, last year.
A crackdown by Chinese police and military in Lhasa on March 14 last year, followed several days of peaceful protests by monks, sparking further waves of protests across Tibetan areas. Exile groups say more than 200 people died in the crackdown.
Overseas activists planned to mark the anniversary with a demonstration in New York, but the official Xinhua agency slammed Western critics of China's rule as misguided do-gooders.
"They might as well bow their heads, mourn those who died in the Lhasa riots last year, and think twice before putting their fingers into something they are ignorant of again," Xinhua said in an English-language opinion piece that appeared aimed at readers outside China.
Why close-off Tibet if all is well?
Tibet and ethnic Tibetan areas of surrounding provinces are under heavy military presence and strictly off limits to foreign journalists and even tourists. Armed police manning road-blocks turned back would-be visitors.
Despite proclamations from top leaders of the ruling Communist government in Beijing that accredited foreign journalists are free to travel and report across China, except in Tibet, members of numerous foreign news organisations have been detained and turned away from Tibetan-populated areas in Qinghai, Sichuan and Gansu provinces with local officials insisting their jurisdictions are closed to foreigners.
A trickle of isolated protests in recent weeks, including a monk who set himself on fire at the Kirti monastery in Western Sichuan, suggest lingering discontent.
Many Tibetans did not celebrate their New Year in February, in silent protest and mourning for those who died last year.
Lhasa residents reached by phone said the day was "like any other", but declined to comment publicly on the security situation, and local government websites had no articles on the topic.
Chinese-language media largely ignored the anniversary on Saturday.
