While India is on track to overtake China as the fastest growing major emerging market in the world this year, the country's finance minister Arun Jaitley says he's not rejoicing yet.

"I'm not unusually excited because I know what China has already achieved. China grew at 9 percent plus for thirty years," Jaitley told CNBC on the sidelines of the Asian Development Bank's annual meeting of its board of governors in Baku, Azerbaijan.
