International fares are submitted for approval to government authorities in the country of origin. This includes a request for the actual fares and the fare rules. The fares are based on the competition ex. that country and what the home government will approve. In addition if a country's currency has decreased/increased against the dollar that can cause wide discrepancies in pricing. Colombo and Tripoli were quite well known destinations from which low business fares could be obtained. The same was true from BKK when their currency took a nose dive. This is not an EK issue. Every airline goes through the same process.
