President Museveni and Japans Prime Minister Shinzo Abe have agreed to push for United Nations Security Council reforms saying the issue was critical for transparency.
The two leaders according to a statehouse statement blamed the current refugee and migrant crisis from Africa and Middle East to Europe.
The say the crisis is partly caused by a few people monopolizing decision making for the whole world.
President Museveni noted that it was not in order to have a small group of countries monopolizing decision making for the whole world.
He said the present chaos in the world is partly caused by that mistake.
He said the invasion of Europe by the Middle Eastern people and Africans as refugees is a product of mistakes made by some actors who are responsible for these mistakes.
Museveni said the huge human suffering and those mistakes must be stopped by collective wisdom.
President Museveni said Africa is insisting on reform of the United Nations Security Council and also having equal rights.
The President who is on a four day official visit to Japan thanked the Prime Minister for the invitation and sympathized with the people of Japan over the floods that hit their country.
Museveni hailed the government of Japan for the support to Uganda over years since 1966 especially in the area of infrastructure development.
He said Japan has done good work in Uganda in the field of electricity, as far as new bridge across the River Nile is concerned, rehabilitation of some hospitals, infrastructure of roads in Kampala and also rehabilitation of northern Uganda after the insurgency.
He commended them to supporting rice projects through developing new variety of rice and encouraged Japanese companies to come and invest in Africa.
Museveni said it would be the best win-win approach when those companies make money, Uganda would also make money and benefit from jobs created.
Japanese Prime Minister Shinzo Abe expressed his heartfelt welcome to President Museveni for the six visits to Japan.
"Museveni is the dean of Africa and an old friend of Japan. Under his leadership, Uganda has achieved and enjoyed successive economic growth since 1990s. Uganda has been contributing to the peace and security of EAC and in this regard, I pay my respect," he said.
Prime Minister Shinzo said he was extremely pleased that they held fruitful discussions and exchanged views with President Museveni and also issued joint statement for the first time.
Shinzo Abe said they had earlier exchanged documents on road infrastructure development project in central Kampala, which he said will form an important basis for Uganda's national development.
He said TICAD, which will be held next year in Africa for the first time, has been attended by President Museveni four times and he has greatly contributed towards its success.
