Mr. Chairman, I believe it is a factor, certainly. There's extensive population movement within the sub-region. There are very large numbers of citizens of one country living in another.
At the same time, for some ethnic groups the population boundaries don't necessarily correspond with the political boundaries between the states. One of the complicating factors in this case is that within Ethiopia, there's a large Somali ethnic community in the Ogaden region. That is an enormously complicating factor.
