Some comments on reported economic performance:
Before too much reliance is placed on reported economic figures for Thailand in the press, it should be noted that most of their reported figures are taken from the Bank of Thailand website who themselves still class many of the figures as "Provisional".
A quick (but by no means comprehensive check) shows that many of the annual figures are "Provisional" going back to 2007, as are quarterly figures going back to Q1 2008 and monthly figures to January 2008 - however, having said that, I do find it a little strange that the monthly and quarterly figures for 2007 are no longer provisional but the annual figures for 2007 still are

(it may just be an administrative oversight on the annual figures for 2007).
With regard to exports (which the media pays a lot of attention to) - I believe that a proportion (but I haven't attempted to work out how much) of the increase in exports reported in the media is actually due to the re-exporting of imported goods for manufacture, if that is the case the improvements in exports may not be anything like as spectacular as reported.
I recently did a comparison of the import and export of goods which (IMHO) showed that imports were rising just as spectacularly as exports.
To get a truer perspective of any improvement in economic performance the re-exporting of "imported costs" should be netted off the export figure.
