I think the answer to the question in general is corruption. I'm sure that if a global player as you put it, or even an enterprising small western company went there looking to set up business, the first government official they came into contact with would have his hand out for a bung and if the said bung was not forthcoming, nothing would get done.
I'm also pretty sure that if they paid the first bung, every other government official they came into contact with after that would follow suit and they'd soon give up trying.
