The most favoured nation clause can also be included in an agreement between a state and a company or an investor. This involves the provision of special privileges and advantages although the state cannot use contractual mechanisms to avoid its MFN treatment obligations with other countries. Unlike the relationship among states where a nation accorded an MFN status cannot be treated less advantageously than another, the host nation does not breach MFN treatment if it provides different privileges to different investors. The United Nations Conference on Trade and Development clarified this when it stated that "a host country cannot be obliged to enter into an individual investment contract" and that "freedom of contract prevails over the MFN standard." This general principle, however, is not absolute.
