Japan is discussing deals to build a train line in the Philippines, a seaport in Cambodia, and a free trade agreement for countries around the Pacific Ocean.
Trans-Pacific trade deal could still go forward
U.S. President Donald Trump withdrew from the Trans Pacific Partnership, or TPP, free trade deal in January. That move left 11 countries including Japan, Vietnam, Malaysia and Singapore wondering how to move forward.
Japan led the remaining countries to a revised deal at a meeting last week of the 21-nation Asia-Pacific Economic Cooperation group in Vietnam. The new free trade deal is called the Comprehensive and Progressive Agreement for Trans-Pacific Partnership.
Japan is also increasing its investment in major Southeast Asian countries. Japanese investment in major countries in the region has averaged $20 billion each year from 2011 to 2016. That is more than double the average from the five years before 2011.
Trade routes and navigation important issues to Japan
Japanese Prime Minister Shinzo Abe was among the leaders at the Association of Southeast Asian Nations, or ASEAN, meeting in the Philippines this week.
The 10-member ASEAN group agreed to upgrade a nine-year-old trade agreement with Japan. A spokesman for Abe, Norio Murayama, said Japan hopes to secure trade routes through Southeast Asia to markets as far away as Africa.
Murayama said, "For Japan, the country surrounded by the sea, a maritime order is extremely important." He raised concerns, however, about the safety of shipping through the region.
Jeffrey Kingston is a writer and instructor at Temple University Japan. He said there are concerns that China may seek total control over navigation in the South China Sea.
"A lot of Japanese investment, a lot of factories' offshore operations (are) located there," he said.
China and Japan seek influence with ASEAN countries
China and Japan still face difficult issues linked to Japan's activities before and during World War II. The two countries also have conflicting claims to some small islands in the East China Sea.
Japanese direct aid around the world increased by 12.7 percent last year to $10.37 billion. The foreign ministry says on its website that Japan is seeking to support the goals of "human security" and "sustainable development." Japan wants to do this based on the needs of individual countries.
China, however, has proposed a huge development program involving hundreds of billions of dollars. Known as the "One Belt, One Road" infrastructure campaign, the project aims to link Asia, Europe and even Africa.
Stephen Nagy is an associate political science professor at International Christian University in Tokyo.
He said Japan's efforts in Southeast Asia will become clearer because the U.S. is currently not as active in the region under President Trump.
Nagy said Japan has an important part to play in developing partnerships in the region. He added that Japan's efforts help balance China's expanding economic, diplomatic and security influence throughout Southeast Asia.
