I would check with the embassy or, if there is one in your city, a consul general's office. Sometimes it is also useful to check with a country's tourism bureau. Another suggestion is a country's economic development office. If you say you are going over on a large business project, that office may be willing to do some leg work for you.
A friend of mine did some similar research on Russia and it wasn't easy to get accurate information. The most useful info he got came from Russian citizens working in the U.S. (bankers, traders, etc.). They gave him advice on what he was likely to encounter in terms of street enforcement.
