The global maritime landscape features massive state-backed shipping enterprises, conglomerate shipowners, and prominent independent fleet operators. Key global giants include massive shipping lines and leasing titans based in China (such as China COSCO Shipping Corporation), Greece (controlling the largest independent merchant fleet globally), Japan (such as Mitsui O.S.K. Lines and Nippon Yusen Kaisha), and Denmark (such as A.P. Møller-Mærsk), which collectively dominate international containerized and dry bulk cargo logistics.
