The White House has announced that first lady Michelle Obama will travel to South Africa and Botswana for an official visit later this month.

The wife of U.S. President Barack Obama will travel to Africa on June 21 for a five-day visit focusing on youth leadership, education, health and wellness.

Mrs. Obama will visit Johannesburg and Cape Town in South Africa and Gaborone, Botswana.

The White House says the trip also underscores the importance of Africa's success to America.

In a statement released on Friday, the United States described South Africa as the continent's political and economic leader and a vital global partner.

It described Botswana as a model of good government for using its vast natural resources to invest in its people and grow its economy.

The first lady will be joined by her mother and daughters Malia and Sasha.
