Prime Minister Shinzo Abe plans to make a three-day visit to Myanmar next Friday in a bid to strengthen bilateral ties, a government source said Saturday.

Abe, who will be accompanied by top executives from more than 30 Japanese companies, is expected to hold talks with Myanmar President Thein Sein on improving the investment environment in the southeast Asian nation so Japanese firms can prosper there.

At the summit with Thein Sein, Abe is also likely to unveil measures to help Myanmar's development. In March, Tokyo announced it will provide Myanmar with yen-denominated loans for the first time in 26 years.
