President Obama’s meeting with the Dalai Lama has already made China extremely angry and stirred up Tibet advocates who thought it should have come sooner. China says Tibet is part of it, and that the meeting represents an unwanted intrusion(侵犯) into its own affairs. Many Americans still see the Dalai Lama as the representative of a people treated cruelly by Chinese rule. Many Tibetans are dissatisfied with Chinese rule, and this has led to widespread rioting(暴乱) over the past few years. Theywantself-determination; fair enough. But that seems to be the only story about Tibet that is ever told. The other story is — Looking at growth, standard of living, infrastructure(基础设施), and GDP, one thing is clear: China has treated Tibetans amiably.

Since 2001, Beijing has spent $45.4 billion on development in the Tibet Autonomous Region (TAR). The effect: double-digit GDP growth for the past nine years. About a third of the money went to infrastructure investment, including the train connecting Beijing to Lhasa. The train provides an opportunity for Tibetan goods to be sold outside of the region and for a massive increase in number of tourists, reaching more than 5.5 million in 2009 — up from close to 2 million in 2005, the year before the train. While Tibetan independence groups like Free Tibet raise concerns about the increase in tourism, Hillman，a Tibet expert, points out that “tourism is an important industry that can benefit local Tibetans.”

Infrastructure improvements have not only helped grow the economy but also have aided in modernizing remote parts of Tibet, an area with 3 million people about twice the size of France.

Though Tibet is seriously puzzled by the "special contradiction" of the Dalai Lama, the central government stressed the need for Tibet to develop using the "combination of economic growth, well-off life, a healthy eco-environment, and social stability and progress" and The government is offering Tibetans the same bargain it has offered the rest of the country: in exchange for a great rise in living standards, the government requires citizens to stop having the right to free worship and free speech. Even if Tibetan residents never signed the contract, they have benefited from its policy—a fact Obama might keep in mind when he meets the Dalai Lama.
