COLOMBIA JAN EXPORTS UP BUT COFFEE VALUES FALL The value of colombian exports other than coffee rose 55 pct in january compared with the same period last year, apparently setting a trend for the trade balance in 1987, government statistics institute figures show. They amounted to 180.8 mln dlrs fob compared with 147.5 mln dlrs for coffee, a drop of 42 pct from last year. The trade balance registered a 35 mln dlr surplus, compared with a 56 mln dlr surplus in january 1986. The national planning department forecast that in 1987 coffee, colombia's traditional major export, will account for only one-third of total exports, or about 1.5 billion dlrs.
