"Sri Lanka hopes to become the regional hub of the Indian Ocean again," Wickremesinghe told a joint news conference following a meeting with his Japanese counterpart, Shinzo Abe.
"We want to ensure that we develop all our ports, and all these ports are used for commercial activity, transparent activity, and will not be available to anyone for any military activity."
Wickremesinghe did not mention any specific countries.
China's investments in transportation infrastructure in Sri Lanka are considered part of its ambitions to build maritime routes to the oil-rich Middle East and on to Europe.
That makes some countries, including India and the United States, nervous. Sri Lanka sits near shipping lanes through which much of the world's trade passes on its way to China and Japan.
"To make this happen, it is indispensable for Sri Lanka to achieve sustainable growth as a hub, and develop ports that are open to all."
