How much can we trust the data coming out of China?
They might be 'massaging' the numbers, or maybe they aren't, but considering the importance of the issue for China and the world, and how many eyes are watching, their interest is still to report factual trends and overall situation. At this point they cannot afford to claim that everything is fine if it isn't. I'm more worried about Iran than China.
Unfortunately it isn't. They are trying to put people back to work and reopen trade because of the damage it is doing to their economy, and massaging the numbers is one crucial element of making that happen.
