Mining industry of Egypt: Mining in Egypt has had a long history that goes back to predynastic times.  Egypt has substantial mineral resources, including 48 million tons of tantalite (fourth largest in the world), 50 million tons of coal, and an estimated 6.7 million ounces of gold in the Eastern Desert.  The total real value of minerals mined was about £E102 million (US$18.7 million) in 1986, up from £E60 million (US$11 million) in 1981.  The chief minerals in terms of volume output were iron ore, phosphates, and salt.  The quantities produced in 1986 were estimated at 2,048, 1,310, and 1,233 tons, respectively, compared with 2,139, 691, and 883 tons in 1981.  In addition, minor amounts of asbestos (313 tons) and quartz (19 tons) were mined in 1986.  Preliminary exploration in Sinai indicated the presence of zinc, tin, lead, and copper deposits.  Private sector exploration and exploitation activities so far have been limited.  Only recently, AngloGold Ashanti with its joint Venture Partner Thani Dubai and a Canadian listed exploration company, Alexander Nubia International have been undertaking exploration in Egypt's Eastern Desert with some success.  Centamin Ltd., a mineral exploration company founded in Australia, started a massive mining project in Sukari Hill.

Mining in Japan: Mining in Japan is minimal because Japan possesses very few mining resources.  Japanese mining was a rapidly declining industry in the 1980s.  Coal production shrank from a peak of 55 million tons in 1960 to slightly more than 16 million tons in 1985, while coal imports grew to nearly 91 million tons in 1987.  Domestic coal mining companies faced cheap coal imports and high production costs, which caused them chronic deficits in the 1980s.  In the late 1980s, Japan's approximately 1 million tons of coal reserves were mostly hard coal used for coking.  Most of the coal Japan consumed is used to produce electric power.

Cotton production in China: Cotton production in China pertains to cotton which is the prime cash crop of China.  Its production is the highest in the world (in excess of 20 percent of world production) since 1982 until recently overtaken by India.  Twenty four of the 35 provinces of China grow cotton with nearly 300 million people involved in its production.  It is the main input for textile industry of the country with cotton textiles now accounting for 80% use vis-a-vis 95% in the 1950s.  The cotton textile industry employs over 10 million people.  Its production in 2012–13 was 7.6 million tons but in 2013–14 it dropped to 7 million tons.  Historically, its introduction in China is considered a 'southernization', crop which originated from southern Asia (India) during the "proto-globalization" period.
