Obama's tour of south Korea is aimed to prod south Korea to recognize Japan's "right to collective self-defense" under the pretext of intensifying the south Korea-U.S.-Japan alliance and demand a conclusion of a military agreement between south Korea and Japan and the increase of the expenses for sharing the upkeep of the U.S. forces, the statement said.

It is a rude act for him to tour south Korea to put pressure on it at a time when people are in grief over the ferry sinking, it charged.

If the "government" accepts the U.S. demand despite the people's opposition, it will meet an all-people resistance, it warned.
