I'm trying to block Chinese visitors from visitng our website

An anonymous reader writes: Ok -HELP !
  we are a small manufacturer and I'm tired of our stuff getting knocked off so I am thinking of a plan of how to block visitors from China from accessing our site and getting "inspired"

1) my first plan was to sense for chinese language browsers but that's not much of a stop gap

2) is there a way to block a site based on ip blocks and if so what are china's ip blocks ?

3) a third and more compelling strategy is to pepper our homepage with links to

Reporters Without Borders
Wikileaks
Falun Gong
Nobel Prize
Tiananmen square massacre
Amnesty International
Central Tibetan Administration
Hong Kong Alliance in Support of Patriotic Democratic Movements in China
Tawain Indepedence
Free Tibet

and hope that our site get's black mailed by chinese censors — any thoughts . experiences ?
