You bring up a great point about the rule of law. This is something that attracts investment, and it's something is close to undefinable. Not being governed in a logical way is business negative, but it's a gray line of when you go from a country ruled by law, and not.
The US has been sort of the gold-standard on this. Most large business disputes are handled in Federal court, which despite the reputation of the government, is well regarded as efficient in the international business world. It's the "rocket docket", meaning cases move. In some countries a business dispute could take 5+ years to get to trial, or resolution. In most Federal jurisdictions, with motions, filings, pre-trial conferences, it's between 12 and 24 months, with many on the lowside of that scale.
There is an untold economic benefit to this. Investors are unlikely to invest large capital outlayws without assurance that if something goes wrong they have an avenue of legitimate relief. Russia and China goes through spurts of foreign investment, but it comes and goes, largely because of this issue. When Putin starts jailing critical corporate executives and nationalizing large businesses it creates a tremendous amount of consternation within the investor class.
This IPO is interesting because it's a test case for how well China can provide a code of laws assurance to the worldwide investor. So far, so good. But the Chineese system has a similar habit of disenfranchising shareholders, and in this case, it could happen in the blink of an eye.
