The Charter 08 document
It helped Liu Xiaobo win a Nobel Peace Prize. Here is one good paragraph of many:
Protection of Private Property. We should establish and protect the right to private property and promote an economic system of free and fair markets. We should do away with government monopolies in commerce and industry and guarantee the freedom to start new enterprises. We should establish a Committee on State-Owned Property, reporting to the national legislature, that will monitor the transfer of state-owned enterprises to private ownership in a fair, competitive, and orderly manner. We should institute a land reform that promotes private ownership of land, guarantees the right to buy and sell land, and allows the true value of private property to be adequately reflected in the market.
