English to German Law/Patents Economics Anti-bribery Policy

Aus der entsprechenden Charta eines internationalen Bekleidungsherstellers. Mir fehlen die passenden Worte:
===
"Charitable donations can in some circumstances be used as a disguise for bribery, for example where a donation is provided to a 'charity' which is controlled by a foreign public official who is in a position to make decisions affecting the company.
Therefore, whilst community support and donations can be made (whether in-kind services, knowledge, ***services exchange***, or direct financial contributions), Employees must be careful to ensure through due diligence and transparency that charitable contributions and sponsorships do not constitute bribery."

Besten Dank im Voraus!
