Because neutral ships also need permission to cross the strait, even if they have not been explicitly banned. Because the status of the blockade has changed and continues to change according to tensions in the region. Several countries have obtained permission to cross: China, Russia, India, Iraq, Pakistan, Malaysia, Thailand, and the Philippines.
