Main Article Content

Abstract

International law requires all states to enact ship registration laws to allocate ships under their jurisdiction, considering the principle of genuine connection.However, international law does not define genuine link, which raises the question of what the state should consider when enacting ship registration laws. The study found that the ambiguous of genuine link led to open registrations and occurred to the problem of flag of convenience, which impacts on the environment, safety and maritime security. This article aims to suggest solutions by determining the minimum of genuine link between flag state and ship, which led flag state can efficiency and effectively enforce law over ship. Meanwhile port state must enforce its own law over the ship that enter into its port to carry out the standard before leaving the port.
