The US, UK, Australian and Japanese governments have already committed close to $150,000,000 combined. That does not include the costs associated with their immediate military assistance (Japanese Navy are helping out, Abraham Lincoln carrier group is on the way, Australian Air Force has been doing around the clock airlifts of supplies etc etc) or emergency supplies they are shipping over. This is just their initial, immediate, cold hard cash being sent to those agencies on the ground right now.
The US, UK, Australian, Japanese and Indian governments are already setting up the plans to coordinate the economic recovery in these countries effected. And when it comes to economic recovery, you know which country will be the main source of support, and the cost of that may well be the largest of them all.
I know here in Australia that the people are opening their hearts and wallets in an amazing way. Millions have been raised by a population of only 20 million. In the business arena, the two largest Australian commercial airliners have donated jets and all the associated flight costs to airlift several plane loads of supplies and medical staff over. The two largest phone companies have said they will not charge the Australian offices of any of the aid agencies involved in the emergency. They will not receive a phone bill for some time. The phone companies have also offered and sent as much equipment and expertise as they can to help communication during the emergency, and help these countries get their long term communication recovery. The list goes on. I am sure there are very similar things happening within the US.
The initial emergency cash & supplies costs are - rightfully so - the whole worlds problem. The long term recovery - as it always does - will come down to only a few.
Sorry, what were the UN and EU up to? $160,000 from France?
