Apkindo chairman Abbas Adhar said that normally Indonesia's exports of logs to China, Malaysia and Hongkong totaled 7 million cu.m. a year.
Now the annual exports were 1 million cu.m. less because of rampant sales by illegal suppliers from Kalimantan and Sumatra, the country's largest producers of timber, Adhar added.
He said that illegal suppliers sold logs below the market price.
Former senior official of the forestry ministry Titus Sarijanto said that theft and illegal logging damaged almost 10 million hectares of Indonesian forests.
