He sent a delegation to Beijing, which ratified the Seventeen Point Agreement without his authorization in 1951. The Dalai Lama believes the draft agreement was written by China. Tibetan representatives were not allowed to suggest any alterations and China did not allow the Tibetan representatives to communicate with the Tibetan government in Lhasa. The Tibetan delegation was not authorized by Lhasa to sign, but ultimately submitted to pressure from the Chinese to sign anyway, using seals specifically made for the purpose. The Seventeen Point Agreement recognized Chinese sovereignty over Tibet, but China allowed the Dalai Lama to continue to rule Tibet internally, and it allowed the system of feudal peasantry to persist. "So even if it were agreed that serfdom and feudalism existed in Tibet, this would be little different other than in technicalities from conditions in any other "premodern" peasant society, including most of China at that time. The power of the Chinese argument therefore lies in its implication that serfdom, and with it feudalism, is inseparable from extreme abuse," "based on serfdom, it was not necessarily feudal, and [Goldstein] refutes any automatic link with extreme abuse." "Evidence to support this linkage has not been found by scholars other than those close to Chinese governmental circles."
