@m-tupu - Yes, GoK will not address price mechanism as long as it is POLITICALLY convenient... nevertheless, the REGIONAL diversification helps KK which can re-route resources, cash, products to markets that are most profitable.
An example:
In 1Q 2011, the KOSF tanks were full of products from a 'connected' OMC. KK had a ship that could not off-load & attracted HUGE demurrage fees.
KK complained to no avail (while there was a shortage of product across up-country incl Nairobi) so it sent the ship to Dar. Other "Kenya-only" firms would be forced to keep the ship at Mombasa.
