North China is currently experiencing record low temperatures this season, with exceptionally low temperatures in the past two weeks, China-based P&I Club correspondent Huatai’s Dalian Office reported on February 1st. It said in a circular that was published by Steamship and Britannia on Friday that the resulting icy sea condition posed a threat to safe navigation in the area.
The key ports affected are those in the Liaodong Bay area, from Dalian to Huludao, Panjin, Bayuquan, Jinzhou and Dandong.
