She main object of this work is to summarise and appraise available information (chiefly frora primary sources) on the mineral resources of China. It must be said at the outset that' the primary information, that is the information from Chinese sources, is far fron ocnplete; moreover, the publication of statistical information in China stopped in I960. A further difficulty is that a substantial part of the resource data seemingly was unreliable. Statistics of agricultural production in 1958 give a striking example of the problem.
In April 1959 the State Statistical Bureau published “Ccronunique on the Results of the Inplementaticn of the National Eocnanic Plan for 1958”, in which it said that the output of food grains reached 375 million tons and increased by 100 per cent over the output in 1957; the output of cotton reached 3.3 million tons and increased by rore than 100 per cent; the increase in output of soybeans was 24 per cent, peanuts 56 per cent and cured tobacco 115 per cent [1, 15.4.59, p.1]. Four months later, in August 1959, the Bureau published seme corrections of the agricultural statistics of 1958, in which the output of food grains was changed to 250 million tens, an increase of 35 per cent against the output in 1957, and that of cotton was changed to 2.1 million tons, an increase of 28 per cent; increase in output of soybeans was changed to 4 per oent, that of peanuts to 9 per cent, and of cured tobacco to
