Bridges reach across the Yalu River, which marks the border between China and North Korea. On the other side of the water, North Korean factories poke into the sky. The bridge on the right was bombed by the Americans during the Korean War to cut off Chinese supplies to North Korea, and replaced by the new one on the left. The contrast between the two neighbours is great. While North Korea suffers starvation and totalitarianism, China has opened its society and has become the world's fastest growing major economy.
