its funny how Qing dynasty ended up so weak towards the end. At its peak, in Kangxi era navy power rivals those of the European power (got this from documentary). Even the ang mos have to give him a lot of faces. But when it comes to puyi, the ang mo just gave him their middle fingers.
Chinese naval power ended after Ming Emperor Yongle and Admiral Zheng He. When Qing took over Ming in China, it was never redeveloped as Manchurians were also landlocked people not interested in the seas. During Guangxu times Li Hongzhang tried to build a Chinese navy but the Japanese navy after beating the Russian navy quickly took the opportunity to declare war and destroyed the the Chinese navy before it could be full fledged. From an objective and strategic point of view, the Japanese were right in their own interest. However, I'm Chinese and of course lament for China. Until today, China as PRC or ROC both don't have proper blue water navy fleets.
