As our fellow witnesses said, there are now issues being raised in terms of asking for troops from various countries. I'm not sure whether specific sanctions would work, because I think it's also an issue related to power structure and relations with local communities.
Also, when we have sexual exploitation and abuse, that's only a symptom of other, broader issues that have to be addressed in terms of how peace support operations, civilian and military, relate to local populations. It's a signal, then, that something else is wrong, which requires further attention and the addressing of these issues.
