2 Between the start of 2006 and the start of 2007, the world price of tea rose from US
$2.00 to US $2.40 per kilogram. A key reason for this rise was an increase in
china's appetite for tea. Demand rose by 13% in 2006 and in 2007 chinese tea

countries would really affect prices". The british drink 165m cups of tea a day and
70m cups of coffee.
