What does Japan have to say China?

Now, Japan and China has a big trouble.
China says, "Senkaku island is our island. That isn't Japan's island."
Many big strikes occurred many places in China.
Chinese people said, "Senkaku island is our island Japan must get way."
Only this problem made a big trouble??????
I don't think so.
China became a big country rapidly. They became rich.
But China isn't a real rich country.
China has many troubles and many problem.
They can't resolve that by themselves.
China need the big help.
Do you know and comprehend their mind?
Their action told us that.
Japan must help China.
