Excerpted from Wikipedia:

The Great White Fleet was the popular nickname for the group of United States Navy battleships that completed a journey around the globe from December 16, 1907, to February 22, 1909, by order of President Theodore Roosevelt. It consisted of 16 battleships divided into two squadrons, along with various small escorts, and earned its moniker for the stark white paint on its hulls.

The fleet's primary mission was to make friendly courtesy visits to numerous countries while displaying new U.S. naval power to the world; Roosevelt sought to demonstrate growing American military prowess and blue-water naval capabilities. Another goal was to deter a threatened war with Japan amid growing tensions around 1907. The voyage helped familiarize the 14,500 officers and sailors with the logistical and planning needs for extended fleet action far from home.

...  The most serious tensions between the United States and Japan came in 1907, leading to widespread speculation among experts that war was imminent between the two. The main cause was intense Japanese resentment against the mistreatment of Japanese in California ... Tensions rapidly de-escalated after the fleet's very friendly reception in Yokohama. Thus, the gesture neutralized the diplomatic trouble that had resulted from anti-Japanese riots in San Francisco. Those problems had been resolved by the Gentlemen's Agreement of 1907 and the fleet visit was a friendly gesture to Japan. The Japanese welcomed it.
