A major Japanese business delegation of around 140 officials, including top executives of big firms, has returned from a six-day tour of Myanmar and Cambodia.

Their focus was chiefly on strengthening relations with Myanmar, but some businesses appear hesitant about entering the country, which is seen as Asia's last untapped market and a target for businesses from China, South Korea and the West.

Japanese business leaders are fully aware of the country's potential, with its population of around 60 million.
