Total previous budget 3.5 million SEK, new budget for today 400 million SEK - no anomaly there...
According to the decision UD2008/10263/ASO (http://s3-eu-west-1.amazonaws.com/openaid/original/Kambodja_samarbetsstrategi.pdf?1300445979) in 2008:
Landallokeringen fÃr Kambodja ska hÃgst uppgÃ¥ till 550 miljoner kronor under strategiperioden. Den Ã¥rliga volymen bÃr vara ca 150 miljoner kronor Ã¥r 2008, ca 175 miljoner kronor Ã¥r 2009 och ca 225 miljoner kronor Ã¥r 2010.
which basically says the maximum allocation to Cambodia should be approximately 150 millions SEK in 2008, 175 millions SEK in 2009 and 225 millions SEK in 2009. This was extended in 2011 until a new decision was made on March 8 in 2012, which can be found here: http://www.regeringen.se/content/1/c6/10/90/38/d0d2fb9e.pdf, which says the aid for 2012-213 should be 400 millions SEK. So, no, there is no anomaly if you bother to do a quick search to get the correct numbers...
It isn't easy being the parent of a six-year-old. However, it's a pretty small price to pay for having somebody around the house who understands computers.
