Some people think that three nations, China, Russia, and Iran, are close friends. They are seen as a group.
But a big problem started. There is a war between Iran, and America and Israel. This is a difficult time, a real crisis for Iran.
During this crisis, people watched to see if China and Russia would help Iran. But they did not get involved. They chose to keep their distance.
This shows that the friendship between these countries has limits. They are not as close as some people believed.
