The trend in the world right now is - not just in developed countries, but in developing countries including China and India - there is a movement to build more and more nuclear plants.

When the world has 1,000, 2,000, 3,000 nuclear plants, can we call that a safe world? I think we need to properly have this debate.

I believe in any country, matters that relate to its territory would, of course, provoke strong sentiments amongst the people of that country.

The safest nuclear power or energy policy is to realize 'zero nuclear power.

So, Japan as a country has lost its vigor, it feels very much closed in for various reasons.

China has become a major presence for most countries around the world but notably for its neighboring countries in Asia. So I think it is a common position for Japan and its Asian neighbors that we certainly would strive to maintain as much as possible friendly relations with China.

In fact, the Senkaku Islands are... inherent territory of Japan that is recognized in our history and also by international law.
