Singapore's January non-oil domestic exports increased 12.8% from a low base last year, official data showed on Wednesday, driven by shipments of specialised machinery, non-monetary gold, petrochemicals and electronics. It marked the quickest pace of growth since June, and compared with economists' expectations for a 5.4% rise, according to a Reuters poll. Exports climbed 6.8% in December, Enterprise Singapore said in a statement. On a seasonally adjusted month-on-month basis, exports rose 7% in January, following the prior month's downwardly revised 4.8% expansion. Economists had forecast a 2% rise.
