ISLAMABAD (Reuters) - Pakistan plans to meet International Monetary Fund officials on Nov 13 to continue talks for the possible release of the sixth tranche of an emergency $11 billion loan, the Finance Ministry said on Friday. The Ministry said it would continue constructive discussions on the release of the tranche of about $1.13b. A government source said the next tranche could be in one or two parts because the current programme ends in December. The IMF is concerned about Pakistans slow implementation of a reformed general sales tax (RGST) and ending energy subsidies. The government also proposes to finalise in the coming days the legislative framework for RGST for submission to parliament, the Finance Ministry said. A government official said that progress would have been made on the sales tax by Nov. 13 and the bill presented to parliament. Final meeting of the provinces (on the sales tax) is scheduled for Monday, the official said. Pakistan also proposed measures to end energy subsidies, but no time frame was given for the actions. The last IMF review was completed in May and the review for the release of the sixth tranche has been delayed since August.
