A foreign or local entity may operate its business in Cambodia through a branch office. Although relatively common in the banking community, the government’s policy, historically, was to limit branches to foreign investors that have executed contracts with the government. Such a limitation is not present under the current law. One notable consideration for branches is that the foreign parent company may be liable for the losses and debts of the branch. Branches cannot hold QIPs and do not have separate legal personality from their principal parent company.
