China never said no one dies, the mistake China made is that back then China intende to tone down that incident to avoid escalating the tension, releasing casualities of both sides may hurt the relations badly and also China worries about the surging nationalism in China will come after it. China still had hope that the two countries already enmity wouldn't deterioate future, only later on found out it was a naive mistake.
Chinese government is a responsible government making every move only after careful study and accessment, unlike Indian brainless politicians who just go ahead and spin lies since day one.
