State minister for International Relations Okello Oryem yesterday described the timing as "still premature" to comment on Tshisekedi's win nor the polls.
An opposition coalition swiftly rejected the vote tally and vowed to launch a court battle that will prolong the country's political crisis. Their most formidable was the Common Front for the Congo, led by Emmanuel Shadary.
Many Congolese objected to Shadary, suspecting that he would allow Kabila to continue to rule from behind the scenes and protect his vast assets.
For a while, it looked like Tshisekedi's name would not even be on the ballot. Tshisekedi garnered just over seven million votes. He participated in negotiations with other opposition leaders to unite around a single opposition candidate, but backed out of a tentative agreement and ran a separate campaign. But with doubts being expressed by runner-up Martin Fayulu, the Catholic church, and the French, it might not be such an easy road to power for the president elect.
The election's supervisors had faced mounting pressure at home and overseas to publish the results after repeated delays stoked fears for the giant country's stability.
The result could still be appealed in the Constitutional Court. That's why the organisation's Belgian representative André Kabanda has defended Tshisekedi, saying the president-in-waiting has the requisite five years' experience.
"Etienne Tshisekedi helped bring about this moment", Tshilumbu said. The government has deployed riot police and other security forces in some sections of the capital, Kinshasa, but the city was reported to be largely peaceful on Thursday.
Supporters of Felix Tshisekedi celebrate in the streets of Kinshasa, Democratic Republic of Congo, Jan. 10, 2019. He will have a lot of influence in determining what happens next.
"If Fayulu and his allies, with their own independent security and financial networks, had taken power they would have changed the power structure of Congo and definitively ousted Kabila and his clan", said Patrick Smith of the newsletter Africa Confidential.
For a long time, Fayulu was ahead in the opinion polls in front of both Shadary and Tshisekedi. He has been declared the provisional victor of a historic election in the country.
The delayed results, almost two weeks after the December 30 vote, came after global pressure to announce an outcome that reflected the will of the people.
And as the country prepares to enter a new era without President Joseph Kabila, who has been in power since the previous incumbent, his father, was assassinated in 2001, the Secretary-General reiterated "the continued support and commitment" of the United Nations. "In 2018, victory won't be stolen from Martin Fayulu". "Mr Tshisekedi knows himself that he did not win". He has suggested that the front may have thrown its weight behind Tshisekedi and pushed him to victory.
Kabila has made no secret of his continuing political ambitions, which is one reason why so many analysts say Fayulu's claims that Tshisekedi has done a deal with the DRC's former ruler may be more than sour grapes.
"Tshisekedi has no capacity to rule, no way of controlling the army or ministerial appointments".
The Catholic Church's bishops conference said last week that it knew the identity of the victor and demanded that CENI publish accurate results.
