Japan will consider its options if the United States seeks cooperation in safeguarding commercial shipping in the Middle East following recent attacks on oil tankers in the area, officials said Wednesday.

Under the bounds of the pacifist Constitution, Japan will likely have only limited options at its disposal, such as providing logistical support under a special law, as was seen in the aftermath of the terrorist attacks on the United States on Sept. 11, 2001, the officials said.

It is uncertain whether U.S. President Donald Trump will turn to Japan for help.
