This book contains the updated papers of the 4th Annual MAA Peter Schlechtriem CISG Conference, which was held on 18 March 2012 in Hong Kong. The contributions cover an overview of the current issues facing the global trade law community such as the expected accession of Brazil to the CISG, the issues facing the CISG with a view to the introduction of the Common European Sales Law (CESL) in the European Union and the effects of reservations made by signatories to the CISG and potential withdrawals of such reservations by such countries. The book is a valuable resource for both academics and professionals working in the field of commercial law, trade law and investment disputes.
