This Declaration commits OECD members to:

• encourage the adoption of privacy policies, whether implemented by legal, self-regulatory, administrative or technological means;
• encourage the online notification of privacy policies to users; ensure that effective enforcement mechanisms are available both to address non-compliance with privacy principles and policies and to ensure access to redress;
• promote user education and awareness about online privacy issues and the means at their disposal for protecting privacy on global networks;
• encourage the use of privacy-enhancing technologies;
• encourage the use of contractual solutions and the development of model contractual solutions for online transborder data flows;
. . .
• support Member countries in exchanging information about effective methods to protect privacy on global networks;
...
• co-operate with industry and business as they work to provide privacy protection on global networks, as well as with relevant regional and international organisations"

This document is perhaps more a demonstration of a lack of agreement than real agreement in the international community. Its principles are broad and do not require common approaches among countries.
