"I will make India a (favourable) destination for foreign investors---(this) 2014 assurance of Modi has come true," BJP state unit President Tamilisai Sounderrajan said in a tweet.
Posting pictures of Modi and BJP President Amit Shah in another tweet, she said "world bank certifies," in an apparent reference to the World Bank rankings.
India had jumped 30 places to 100th position in the World Bank's 'ease of doing business' ranking, helped by a slew of reforms in taxation, licensing, investor protection and bankruptcy resolution.
In its annual report 'Doing Business 2018: Reforming to Create Jobs', the World Bank had said that India's ranking reflects nearly half of the 37 reforms, adopted since 2003, implemented in the last four years.
