China is reported to have cancelled a long-planned visit to China by members of the Dalai Lama's government-in-exile. The US-based Radio Free Asia reported that China had opposed the visit because some members of the delegation had engaged in what it described as 'splittist' activities.
Neither the Dalai Lama's office nor the Chinese Foreign Ministry have commented on the report.
China has ruled Tibet since it occupied the Himalayan region in 1951.
