     All Asian people should remember what Japanese did in the 1930s and1940s.

     On April 22, 2005, Japanese Prime Minister (首相) Junichiro Koizumi said sorry for his country's past

in the wars. "In the past, Japan brought great damage and suffering to many people of those countries,

especially those in Asia," he said. 

     He was talking to 100 Asian and African leaders at a meeting in Jakarta, Indonesia. China and Japan are

having a hard time these days. China is angry at Japan because Japan doesn't face its past. 

     For example, Japan started the wars with China in the 1930sand 1940s. But one of its new history

textbooks says China started the wars!

     Chinese President Hu Jintao met Koizumi on April 23. Hu said 中国想和日本做朋友. But he also told

Koziumi that Japan needed to use the history as a mirror and face the future.

     China and Japan are both important countries in the world. The two leaders agree a good friendship will

be good for both countries. 

     These two countries sold s lot of goods to each other. Koizumi's apology is a good start. Now it's

important for Japan to match its words with its action.
