The customer's relocation and expansion to different jurisdictions constitutes a triggering event that requires ongoing due diligence on this client, as it may indicate changes in the customer's risk profile, business activities, or beneficial ownership. The bank should update the customer's information, verify the identity and legitimacy of the new entities, and assess the level of money laundering and sanctions risks associated with the new locations12. The other options are not triggering events, as they are either consistent with the customer's normal business operations or do not affect the customer's risk profile.
