LONDON, Feb 22 (Reuters) - Robusta coffee futures fell on Wednesday as Brazil backtracked on plans to allow imports into the country for the first time, while raw sugar edged higher as technicals supported.
COFFEE
* Robusta coffee slipped, with the May contract down $20, or 0.91 percent, at $2,169 a tonne by 1456 GMT, after earlier slumping 2.2 percent to a session low of $2,141.
* The weakness came after Brazil's President Michel Temer ordered a suspension of the authorisation of robusta coffee imports late on Tuesday.
* Brazil was poised to allow imports of 1 million 60-kg bags of coffee from Vietnam at a 2 percent tariff for the first time under a decree outlined this week.
* "For me, for anything like this to go through, it's got to be a desperate situation," one dealer said, noting a recent fall in internal prices suggested this was not the case. "It shows you there's coffee there. They just need a bit of pressure to sell it."
* The imports were meant to ease a supply squeeze after two years of drought in top producing state Espirito Santo, which has hit the country's soluble coffee industry.
* Local robusta producers have opposed the move, maintaining there is enough domestic supply to meet demand.
* May arabica was up 1.15 cents, or 0.76 percent, at $1.53 per lb.
SUGAR
* March raw sugar was up 0.08 cents, or 0.39 percent, at 20.82 cents per lb, after earlier climbing to 20.94.
* Dealers said technicals supported, as prices rose above the 200-day moving average. But gains were limited as the market struggled to move past the next resistance level.
* The front month climbed 2.4 percent the previous day on tightening nearby supplies, highlighted by physical purchases from Egypt and Iran.
* The International Sugar Organization on Tuesday trimmed its sugar deficit forecast for 2016-17 but also noted dwindling global stocks will help support prices after the market comes out of deficit in the 2017/2018 season.
* May white sugar rose $2.50, or 0.45 percent, to$563.10 a tonne.
* The white sugar premium remained near the 3-month high touched a day earlier, supported by demand from Myanmar, seen as a route to China, and expectations of Indian imports later this year.
COCOA
* May New York cocoa was unchanged at $1,996 a tonne, while May London cocoa fell 5 pounds, or 0.31 percent, to 1,609 pounds a tonne. (Reporting by Mariana Ionova; editing by
