 China also treats the invasion as part of its "century of humiliation" at the hands of Western and Japanese powers and the defence as a Chinese resistance.Meanwhile, many Tibetans look back to it as an exercise of Tibetan self-defence and an act of independence from the Qing dynasty as the dynasty was falling apart, and its growing disdain to China in the aftermath due to ruthless repression of Tibetans at 1905.The historian Charles Allen, while disputed, has apologetically remarked that, although the Younghusband Mission did inflict "considerable material damage on Tibet and its people", it was damage that paled into insignificance when compared "to the invasion of Tibet by the Chinese People's Liberation Army in 1951 and the genocidal Cultural Revolution of 1966–1967".
