My guess is that the slight strengthening of the Baht due to last week's revaluation of the Yuan is a short term thing and that it won't do anything to halt its decline to around 44 baht for the dollar, 35 to the Aussie dollar.
As someone else said, the Yuan cross-rate developments pale into insignificance when you compare it to other fundamentals such as the impact on Thai competitiveness as a result of higher oil prices.
I have noted that the effect of this revaluation of the Yuan against the SGD has been in the order of a few hundredths of a point, not enough to take notice unless you are shipping huge amounts of money around...
