Since 2013, it has been three years of my experiences involving a lot of local market research to support Japanese companies in advancing their business into Cambodia economies and markets. Those industries included factories, companies, agencies, agri-products, universities, restaurants, wastes recycling, recycling products, etc. There are some collaborative colleagues like my team to do such complex works. They try very hard to cope with the difficulties. I am very thankful to them despite some stay within short and leaving, some not, etc.
