Ugandan President Yoweri Museveni on Saturday received his Kenyan counterpart William Ruto at Entebbe International Airport, ahead of Kampala's celebrations to mark 60 years of independence from Britain.
But the anniversary had been marked with tensions between the two neighbouring countries after Museveni's son, Gen Muhoozi Kainerugaba, last week issued a series of tweets that derided Ruto's election and joked about the ease with which his troops could capture Nairobi in two weeks.
President Ruto's team had threatened to skip the ceremony over the tweets unless an apology came but even after that, it was expected that the two leaders would hold a bilateral session in Kampala on Saturday to discuss the issue.
Uganda is Kenya's biggest trading partner with Kampala relying on the Port of Mombasa for most of its imports.
The trip is Dr Ruto's first to Kampala since he was elected President and the Supreme Court validated his victory last month. Prior to travelling to Uganda, he was in Addis Ababa for the launch of Safaricom Ethiopia. He is also scheduled to visit Tanzania in this first regional tour.
