COCOA
* March London cocoa was up 41 pounds, or 2.4 percent, at 1,745 pounds a tonne by 1425 GMT, after climbing to 1,761 pounds per tonne, the highest for the front month since July 18.
* Dealers said the London market was lifted by arbitrage-related buying by speculators, following a holiday closure during New York's rally on Wednesday.
* "London is just catching up today," said one European dealer.
* March New York cocoa was down $50, or 2.1 percent, at $2,379 a tonne, after falling to a session low of $2,349 a tonne.
* This wiped out some of the gains made the prior day, when prices surged more than five percent to $2,436, their highest since mid-July.
* Dealers pegged Wednesday's rally on a wave of chart-inspired trading but noted the speculative buying had waned, triggering a correction.
* "The move yesterday was clearly exaggerated," the dealer said. "But the funds seem to want to be long. They're moving towards being net long."
* Fundamentally, market focus remained on Ivory Coast where favourable weather and strong port arrivals continue to signal a large crop this season.
* However, dealers noted industry buyers remained well covered and were mostly on the sidelines.
COFFEE
* March arabica coffee fell 1.15 cent, or 1.1 percent, to $1.0275 per lb, giving up some of Wednesday's gains.
* Dealers noted prices were partly weighed down by the weaker Brazilian real. It encourages producer selling by improving local returns on dollar-traded commodities like coffee and sugar.
* Prices also remained under pressure from expectations for ample supplies, which helped push the spot contract to a three-month low of 98.60 cents last week.
* March robusta coffee was unchanged at $1,515 a tonne.
* Vietnam's coffee export volumes for 2018 are expected to rise by 20.1 percent from last year, government data showed on Thursday.
* Vietnam is the world largest robusta producer. Farmers have picked nearly 85 percent of the 2018-19 harvest, which is expected to end mid-January.
SUGAR
* March raw sugar was down 0.06 cent or 0.5 percent at 12.33 cents per lb, also weighed down by the Brazilian currency.
* March white sugar fell $0.30, or 0.1 percent, to $337.40 a tonne.
