Congo's leader says he's committed to holding November's presidential election on time.
President Joseph Kabila spoke to thousands of supporters Wednesday, saying the vote should be credible and democratic.
Kabila took office in 2001 after his father's assassination. He was formally elected in 2006 in the vast Central African country's first democratic vote in 40 years.
He has pushed through a series of constitutional changes to strengthen his powers, replacing a two-round voting system with one winner-takes-all round.
Analysts anticipate that if the opposition vote is split among several candidates, Kabila will be re-elected.
Congo suffered back-to-back civil wars and the country's east remains mired in conflict.
