China has lodged protests against the Japanese government for its tolerance of the Dalai Lama's anti-China separatist activities in Japan.

Analysts say the collusion of the Dalai Lama and the growing number of Japanese right-wing forces will add tension to already strained China-Japan relations.

Foreign Ministry Spokesman Hong Lei condemned the Japanese right-wing forces' "blatant support of the Dalai Lama's anti-China separatist activities", which have "infringed upon China's internal affairs".
