The U.S., Canada, Japan and eight European nations are considering imposing travel bans on unidentified Kenyan officials responsible for the African country’s widespread corruption, diplomats in the capital said.

“People shouldn’t enjoy the benefits of ill-gotten gains in London or Geneva or anywhere and we will assist Kenya in any way to stop this,” U.K. High Commissioner to Kenya Christian Turner told reporters Thursday in Nairobi.

Corruption “deters investment and costs jobs,” U.S. Ambassador to Kenya Bob Godec told reporters, reading from a joint statement after meeting officials from Kenya’s Ethics and Anti-Corruption Commission. The group of 11 diplomats, who also included representatives of Finland, France, Germany, Sweden, Norway, the Netherlands and Switzerland, pledged to help Kenyan authorities recover any stolen assets from their respective countries.
