The move came on the back of UPM signing a letter of intent to become sole owner of Botnia's Uruguayan Fray Bentos mill and forest plantations.
The paper giant will increase the share of plantation-based eucalyptus pulp sourced from the country for use in the paper production of its Changshu, China-based paper mill.
UPM, which informed APRIL of its decision at the beginning of the month, had previously sourced pulp for its Changshu fine paper mill from APRIL and, from the beginning of 2004, the mill received pulp solely based on acacia from plantations.
UPM terminates APRIL pulp agreement
UPM has terminated its existing purchasing contract with Asia Pacific Resources International Holding Limited (APRIL) as part of its new pulp sourcing strategy.
