What is wrong with people who want to help?

Today I heard news that Indonesian parliament had a bad thought about a foreign soldier that were helping in tsunami place in Aceh. Why would they said something like that? I don't have idea if the aid was filled with political motivation. From what I have heard from others, they were helping much in the remote area and they are more decent in handling the corpse than our own volunteer. So why should they being judged with hidden agenda? I don't know what happened to them.
