The  main products Cambodia shipped to Japan were garments, sugar, fish and seafood. In return, the country bought machinery, automobiles, electronic products, meat, iron, steel and pharmaceutical products from Japan.

On the investment side, Japanese firms have begun to focus their investment in Cambodia in recent years. According to Japanese Ambassador to Cambodia Masafumi Kuroki, Japanese investors have invested about $300 million in Cambodia in the last three years.

Kuroki said that Japanese investors' confidence in Cambodia has increased thanks to Cambodia's full security and political stability.
