Police in Nepal Thursday detained at least 760 Tibetan exiles who were protesting outside the Chinese embassy in Kathmandu.
Witnesses say police scuffled with some protesters, many of whom were hauled away in police trucks.
Nepal is home to about 20,000 Tibetans who fled their homeland after a failed uprising against Chinese rule in 1959.
Exiles have been staging near-daily protests since March, when Chinese forces brutally suppressed demonstrations in the Tibetan capital, Lhasa.
Activists have intensified anti-China protests recently, to coincide with the Olympic Games in Beijing.
On Friday, the night of the Olympics opening ceremony, Nepalese authorities detained some 1,300 protesters in Kathmandu.
