Prime Minister Shinzo Abe said he sees no need to explain to China and South Korea his cherished goal of rewriting the pacifist Constitution.

"It is our country's Constitution, so it is not an issue that needs to be explained" to China and South Korea, Abe told reporters Wednesday accompanying him on his visit to Saudi Arabia.

Abe said that to achieve his goal he will aim to secure a two-thirds majority in the Upper House in this summer's election.
