Finance Minister Lim Guan Eng says Putrajaya has been successful in managing the impact of price rises with implementation of the sales and services tax (SST).Responding to a survey by the Federation of Malaysian Manufacturers (FFM) and the Malaysian Institute of Economic Research (MIER) as reported by The Star today, Lim said he disagreed with the findings but didn't deny that there were issues caused by the rapid implementation of the SST.
