The World Bank says export volumes of coffee and cocoa from Papua New Guinea have dropped during the four quarters up to June this year.
The bank, in its PNG economic briefing, says export volumes of coffee were down 50 percent, while cocoa exports were 30 percent lower.
According to the Post Courier newspaper, the report says the low volumes combined with lower prices, reduced the Kina value of coffee and copra exports by almost two-thirds, and cocoa exports by 40 percent, despite the support to kina receipts from the currency's depreciation.
Coffee exports for the year to the June quarter 2013 of 317 million Kina were the lowest since 2007, while cocoa export receipts of 143 million were the weakest since 2002 and compare poorly with average annual receipts of 267 million for the last decade.
