Siwelele will be facing AS Maniema Union of the Democratic Republic of Congo in the preliminary round of the 2020/21 competition.
The first leg will take place from 27-29 November this year.
John Maduka's side qualified for the continental competition after finishing as runners-up in last season's Nedbank Cup.
"You know what, I think as a team and again for the people of Bloemfontein, I believe that team is a big team and for them to showcase their talent in Africa is a good thing for them in terms of growth so that people will know about Bloemfontein Celtic of South Africa," Kukame tells snl24.com/kickoff.
"With Celtic going out there, people will know there is a team called Celtic. It's going to benefit Bloemfontein as a whole, and it's going to promote the Celtic brand you understand.
"But when I look into their affairs right now, for me I don't think it's a good idea because I believe with the information that I've got, there are a few players that are still waiting for their promised agreement from the management. But I don't want to dwell more on that because I don't have facts."
Kukame continues: "Yah but from a distance, from the rumours and from the close people I talk to, they are telling me that there are those financial problems. Up until there's a sponsor or somebody who will be able to pump money into Celtic... it would be a good thing, then they go to Africa.
"But for now I don't think it would be a good idea for them to go there while suffering like they do when it comes to money.
"Remember, Kaizer Chiefs once cancelled the Confederation Cup because of what? Imali. Can you imagine a big team like Kaizer Chiefs cancelling a tournament? Then imagine Celtic with their financial problems... it's going to cost them more.
"Unless they have money. If they don't have money, they must write a letter asking the League to find another team to replace them. If I had money I would give it to them and say, 'Celtic, go and play.' Remember, if they do well the country benefits, our football benefits."
