Khieu Samphan’s character
Tun Soeun described Khieu Samphan as an honest, gentle, and very loved person.
28
He stated that Khieu Samphan does not discriminate against anyone and has good rapport with his neighbourhood.
29
For Tun Soeun, Khieu Samphan is a very simple person who educated his children to be modest, good, and law abiding.
30
Khieu Samphan gave him advice on how to work hard to earn their living and how to do farming.
31
Also, Khieu Samphan was loyal to the nation, was not greedy, and did not want to enjoy any excessive power.

While working at the Ministry of Foreign Affairs, Khieu Samphan’s aim was to reconcile the three parties in order to achieve peace for the nation.

They never discussed Khieu Samphan’s past during the Democratic Kampuchea period.
35
When questioned about Khieu Samphan’s political beliefs, Tun Soeun stated that Khieu Samphan did “his best to follow whatever former prince, Norodom Sihanouk, wanted him to do.”
36
The Trial Chamber cited Tun Soeun’s testimony when evaluating Khieu Samphan’s sentence.
37
However, it considered that the fact that Khieu Samphan had been kind to people could not play any significant part in mitigating crimes of the severity of those for which he had been found guilty.
38
In his Appeal brief, Khieu Samphan argued that the Trial Chamber erred by not considering his good character reflected by the character witnesses’ testimony, such as Tun Soeun’s testimony.
39
The Supreme Court dismissed this ground of appeal, finding that it is evident that the Trial Chamber considered Khieu Samphan’s character as a potentially mitigating factor.
