I may have a problem with the interpretation, but I think you understood me.
I will explain as best I can the role UDSP representatives play outside of the country.
UDSP Canada is a civil organization based in Canada whose purpose is to inform the Government of Canada and the Canadian public about the situation in the Congo, and it tries to influence them in the right direction, which is the direction of change.
The UDSP has been fighting since 1982 for political change in the Congo. The party advocates for a respectful, law-abiding state, one that will respect not only human rights, but also the normal missions of a country, the first of which should be to ensure the safety of its citizens. If such a state could be set up, we would see good participation of civil society in the economy and the proper functioning of the country.
To my knowledge, this is also what UDSP militants advocate in other countries. They generally work in co-operation with other Congolese groups, even if they are not part of UDSP.
I will now answer the second question concerning the dangers these people face when they go back to the country.
Some of them are well-known for having spoken out openly or opposed the country's political system. Generally, there is a file on those people in the country. If they go back there, they may well be harmed, and may be kidnapped or killed in a way that cannot be traced back to the state. It will be made to look like an accident or a kidnapping; and then people will say that the person just disappeared. Those are the risks those people face. However, there are less visible actors who can go back to the country without running into too many problems.
I don't know if I answered your question properly. If you need further clarification, I can continue.
