Well... I actually disagree? There are a lot of gradations between
-- full, totally functional democracy with very strong rule of law, like Switzerland
-- absolute, practically lawless dictatorship like Saudi Arabia
China is one of many, many countries which is somewhere in between.
Frankly, so is the US.
There are various "democracy rankings". The Economist did one in 2010; Saudi Arabia was at rank 160, 7th from the *bottom*, keeping company with Equitorial Guinea, the Central African Republic, Myanmar (which is committing multiple genocides), Uzbekistan, Turkmenistan, Chad, and North Korea. China was up at rank 136, near Azerbaijan, Egypt, and Vietnam because it has a political culture and political participation.
The important point for this purpose is that China has an extremely strong, and very old, legal tradition. Despite one-party rule, people can get absolutely furious, and fight in court a lot, if property is taken without proper procedure and compensation, or if laws on the books are not enforced (as was happening with the environmental laws until recently). A lot of the fight for human rights in China is done by lawyers fighting to enforce laws already on the books. And judges *do* rule against the Chinese government.
Saudi Arabia officially doesn't *have* laws on the books. They claim that the Koran is the Constitution and use Sharia for most rulings, supplemented by royal decree. This wouldn't be so bad if they used any of the traditional Islamic systems of jurisprudence (which ended up being quite a lot like English common law in many ways). But they don't. Because the extremist Wahhabis have controlled the legal system in Saudi Arabia since day one, they have ended up with a system where the judges are not bound by precedent or text or legal tradition, and simply act as agents of either the Wahhabis or the king.
Given this, which country is safer to make a business deal with?
A battery deal would be OK. Saudi history treatment of workers is worse than China (workers actually do have substantial rights in China -- and generally no rights at *all* in Saudi Arabia), so I'd be uncomfortable with a factory.
