The recent disasters that hit both China and Myanmar are actually devastating on scales we could not imagine. To put it into perspective, if Brunei had the same disaster, half the population would be dead, and 40% of the remaining population would be missing, and the rest would not have had a home. Myanmar's population is certainly not the biggest, which would mean that while percentagewise it would not sound as disastrous as what it would have been like if it was Brunei, but this is not statistics, this is human life.
The most important thing, everyone wants to help, just as everyone wants to support China. China could get applause for how it is handling the disaster, but it is getting criticism for having shoddy infrastructure in the first place. This openness and transparency (or to the most that China will be willing to present) gives us an idea, however small, of the picture of the disaster, and how we can help out.
Myanmar, on the other hand, is a largely worrying situation. We are all definite and certain that the death toll is largely understated, and for a country with no means or proper infrastructure available to rescue all that could possibly be rescued, or nurse the injured and critical back to health, things cannot get better.
