What is the biggest weakness of the Chinese government?

The biggest weakness of the Chinese government is that they exist in an increasingly modern world but they wish to operate with a form of dictatorship. They wish to hold ultimate power, but in this realm of technology and the world moving forward, they are in a difficult situation.
On one side, they are busy working the "system" to be productive in the world market. They are developing their manufacturing to compete with the best in the world. They not only compete, but also outrun the competition. But what are the people to do? They remain in darkness, under the control of a dictatorial government. They are also working on developing the technology side as well, but they want to keep the people under control.

The problem with this feature is this that as the people become more tech savvy and as the country relates with the rest of the world, there is no way for them to keep control as they have been doing. If they stayed away from the rest of the world, they may have been able to accomplish what they want to do. But this is their greatest weakness.
