The Qing dynasty was seen to be the return of Chinese expansionist policies. Under the Qing rule, China expanded beyond the Great Wall and started to annex more territories in process. The Qing invaded Korea, managed to conquer Mongolia, and also annexed modern territories of Xinjiang and Tibet as well. The Qing also managed to extend its control into Central Asia for once more, mostly concentrated in what would be today Kazakhstan, Kyrgyzstan and Tajikistan. The Qing also destroyed the Kingdom of Tungning of Koxinga, and annexed Taiwan as well. This marked for the first time, China managed to directly control Xinjiang, Taiwan, Tibet, Central Asia and Mongolia. China also marked its claims far to Sakhalin, even though the Qing didn't manage to control it; or even to Kashmir where it fought a bitter war against the Sikhs.
