The changes, which have been evident since the annexation of Tibet by the People's Republic of China in 1950–51, have been facilitated by a range of economic, social, cultural, religious and political reforms which have been implemented in Tibet by the Chinese government. Critics cite the government-sponsored migration of large numbers of Han Chinese into the Tibet Autonomous Region, deemed Chinese settlements, as a major component of sinicization. Some academics have described it as a form of Han settler colonialism.[1][2][3]
The Chinese government claims that its policies have benefited Tibet, and it also claims that the cultural and social changes which have occurred in Tibet are consequences of modernization. According to the Chinese government, Tibet's economy has expanded; improved services and infrastructure have improved the quality of life of Tibetans, and the Tibetan language and culture have been protected.

China's 'ethnic unity' bill aimed at complete sinicization of the Tibetan plateau through ethnic cleansing: CTA Information Secretary, (15 January 2020), https://tibet.net/chinas-ethnic-unity-bill-aimed-at-complete-sinicization-of-the-tibetan-plateau-through-ethnic-cleansing-cta-information-secretary/Archived 10 October 2021 at the Wayback Machine ["China has waged unceasing campaigns at both central and local government level to aggressively consolidate its military occupation of Tibet in the last more than six decades. But this new state-sponsored regulation is seen as a desperately contemplated measure to curb the undiminishing defiance of the Tibetan people and their call for the protection of their identity, for freedom, human rights and for the honourable return of His Holiness the Dalai Lama to Tibet." "Central Tibetan Administration's Information Secretary Mr T.G. Arya condemned the new ethnic identity law, calling it a measure of ethnic cleansing aimed at complete sinicization of the Tibetan plateau. The Secretary also criticised the legislation as a gross violation of the international law and the Chinese constitution." " "What China could not achieve through the sixty years of occupation and repression, now they are trying to achieve it through repressive law. The law aims to achieve complete sinicization of the Tibetan plateau through ethnic cleansing. China finds Tibetan language, religion and culture as the main barrier to achieving complete control over the land," Secretary TG Arya told the Tibet News Bureau.]
