Transparency International [3], the corruption-monitoring organization, has issued two new reports looking in particular at corruption in the military world, and it will come as no surprise to learn that The Bug Pit's coverage area fares poorly.
One report [4] (pdf) examines corruption in government defense institutions (e.g., defense ministries and armed forces). The second [5] (also pdf) looks at corruption in the defense industry. In both reports, countries and companies are placed in six categories, A to F, where A represents a "very low" potential for corruption and F means a "critical" risk of corruption.
Not every country in the region is surveyed, but among those which are, China, Georgia, Russia, Kazakhstan, and Turkey all fall in the D ("high risk") category, while Afghanistan, Iran, and Uzbekistan are in the E ("very high risk") list. On the list of companies, Turkey's Aselsan and Russia's Gorky Automobile Plant are in the E group, while everything else, including all other Russian, Chinese, and Turkish companies surveyed, are in the F group. In a region where you have to celebrate small victories, it is perhaps worth noting that in the F group of countries, not a single Eurasian country joins the rogue's gallery that includes Eritrea, Syria, and Yemen.
The list of countries surveyed is somewhat disappointing: both Armenia and Azerbaijan have gone on some pretty aggressive weapons buying sprees in recent years (much more so than Uzbekistan, for example), so it would have been worth looking at those. Though, of course, there is nothing to suggest that their results would be any better than those of their neighbors.
