In May 2004, the then President of the Republic of Zambia, Levy Mwanawasa appointed Tembo as Zambia’s Chief Trade Negotiator and Director of Foreign Trade in the Ministry of Commerce, Trade and Industry. One of her key responsibilities during this period was to lead the Zambian technical team in its capacity as coordinator of the group of Least Developed Countries (LDCs) during the World Trade Organization Ministerial Conference of 2005. Among the agreements reached in Hong Kong was the decision to extend duty and quota-free market access to LDCs and the Aid-for-Trade agenda, an initiative that seeks to place a spotlight on the role of trade related capacity building in supporting growth and sustainable development with the aim of ensuring for poverty reduction. A key feature of this was the establishment of the Enhanced Integrated Framework, a multi-donor initiative hosted by the WTO.
