MANILA (Reuters) -President Ferdinand Marcos Jr said on Monday the Philippines would not use water cannons or any offensive weapons in the South China Sea, and the last thing it wanted was to raise tensions in the strategic waterway. "We will not follow the Chinese coast guard and Chinese vessels down that road," Marcos told reporters, adding the mission of the Philippine navy and coast guard was to lower tensions, and there no plans to install water cannons on vessels. China's embassy in Manila did not immediately respond to a request for comment.
