 2002 Sino-African SHP Training Workshop
       he 2002 Sino-African SHP Training Workshop was held from 10 May to 18 June 2002 at
 T     Hangzhou Regional Center for Small Hydro Power(HRC). Attended altogether 9 partici-
pants from 5 African countries, i.e. Burundi, Nigeria, South African, Tanzania and Tunisia. This is
the second training workshop on SHP that HRC conducted for African countries. Last Oct and
Nov HRC held the SHP training for participants from Africa where the majority of the population
has no access to electricity yet. Meanwhile, it is abundant in hydro power resources in Africa and
around 10% of its hydro power potential has been harnessed according to the statistics available.
     This training workshop was sponsored by Chinese Ministry of Foreign Trade and Economic
Cooperation, as one of the technical collaborative projects among the developing countries. All
the lodging, boarding, training, pocket money and the domestic transportation fees were borne by
the Chinese government. This is part of the Chinese contribution to South-South cooperation.

                           and planned that recently 40 medium and small-sized hy-
                           dropower stations are to be tapped, among which there
                           are 15 stations with the installed capacity of 0.5-7MW,
                           and 25 stations with the installed capacity of 9-100MW.
                           In the past, in Vietnam the medium and small-sized hydro-
                           power stations are all invested by the state, and now more
