中朝交流史中,山东一直占据着重要位置。山东半岛古代的三大通商口岸——莱州港、登州港、密州港,一直是中国北方对朝鲜半岛及日本海上交流的主要窗口。中国古代的海上丝绸之路,其中一条重要线路便是从山东半岛的东部起航,经朝鲜半岛沿海地区,再去日本或俄国。政治、经济、文化等各个方面的交流,也在这两座半岛上留下了彼此的痕迹。儒 In the history of exchanges between China and North Korea, Shandong has always occupied an important position. The three ancient ports of commerce in Shandong Peninsula, Laizhou Port, Dengzhou Port and Mizhou Port, have always been the main windows for northern China to exchange information on the Korean Peninsula and Japan. In ancient China, the maritime Silk Road, one of the important routes, started from the eastern part of the Shandong Peninsula and headed for Japan or Russia via the coastal areas of the Korean Peninsula. Political, economic and cultural exchanges have also left traces on each other on these two peninsulas. Confucianism
