In April 2004, an official of the Shandong province raised the possibility of constructing a canal between Jiaozhou Bay and Laizhou Bay as a means of easing the pollution problem in the Bohai Sea. The proposed canal will also be open to ships traveling between Bohai Sea and the Yellow Sea. A meeting held in Qingdao in October, 2006, was attended by more than a hundred members of academia.
