This book predicts possible international changes that may occur between 2013 and 2023. It forecasts that China will become a global superpower no later than 2023, and that a bipolar world will be formed with a strategic rivalry between China and the US. China may also further reduce the disparity in capability with the US, while other major powers will witness an enlarged capability gap with both China and the US. Therefore, this bipolarization will drive the world center to shift from Europe to East Asia.
