its not china biusness
It was not the business of foreign forces to create the State of Israel on the Palestinian Land in 1948. They didn't get the mandate for that.
At that time UN created the borders of Israel and resolutions were passed.
After these UN resolutions, it is indeed a business of China and Europe and whole world to tell Israel to go back to the pre 1967 borders and stop the illegal settlements and let the Palestinians decide their fate themselves.
