Stabilisation measures: are not short term measures, intended to correct of the weaknesses that have developed in the balance of payments and to bring inflation under control.

i don't understand this?

The actual statement in the book states Stabilisation measures as "short-term" measures which are taken to improve BOP and control inflation.As part of New Economic Policy,stabilisation measures were proposed to help an economy keep sufficient foreign exchange so that there is no hindrance in form of unfavorable BOP.When a country has ample foreign exchange reserve,it is able to make payments to other countries and save itself from negative BOP.

The other reason for suggestion of the measures is to have control over inflation.The measures help economy to check price rises.
