Russia faces losing all its ships if it continues to strike Ukraine's ports, President Zelenskyy said.
The attacks have killed civilians, but in recent weeks Ukraine has hit back with sea drones.
Zelenskyy's comments were published days after Ukrainian exploding sea drones struck a Russian oil tanker and a Russian warship.
Since then, Russia has ramped up its attacks on Ukrainian ports, killing some civilians and making one strike just a few hundred yards from the border with Romania, a NATO member.
Ukraine made a similar declaration about ships traveling to Russian-controlled ports, and in the interview published Sunday, Zelenskyy vowed to respond to any attacks on Ukraine's civilian populations.
