1. WTO trade ministerial negotiations follow the principle of a single undertaking, meaning that once negotiations on all the aspects have been concluded, countries are able to adopt them. Therefore, though some negotiation issues may have been successfully concluded, these cannot be implemented until agreement is reached on the remaining issues. The “Early Harvest” was proposed as a means to enable LDCs to benefit from the early consensus on some issues, recognising that the single undertaking could take longer than expected. See ICTSD (2010).
