He urged the Democratic Republic of Congo’s leader to respect the rule of law and freedom of assembly.
“The president of DRC must comply with the rule of law and abide with the constitution,” Khama said.
Khama in his speech urged African countries to benchmark on Botswana and implement democratic principles in their respective nations.
The 64-year-old has been president of the landlocked southern African nation since April 2008.
President Kabila failed to step down after his term ended in November 2016, as the country failed to conduct elections to find his replacement.
The electoral authority said then that it was not in a potion to conduct the vote due to logistical challenges.
In early 2017, it said it needed more time to register more eligible voters to participate in the election, later giving a mid-2018 timeline for the vote.
Opposition leaders however took issue with the delay, blaming Kabila to have been behind it all in a bid to cling on to power.
The failure to hold the elections sparked clashes in Kinshasa and other major towns, with anti-Kabila protestors engaging security forces in battles on the streets.
