Though Williamson added Pakistan and Sri Lanka as other teams who can aim for the title, he was quite confident about MS Dhoni's men as he tipped them favourites to win the title this year.
The youngster also warned teams not to write off New Zealand as they also have chances.
"It's going to be a difficult challenge for the non Asian sides in Sri Lanka. Having said that though I feel we have the players who can do well in those sorts of tournaments like we showed in the World Cup last year."
Williamson said, New Zealand is also a good side and the entire team will be excited about playing the mega event and was confident that Kiwis can win over their opponents on their day.
"The boys will be really excited and we know we can beat anyone on our day. The key is to keep on looking to improve and we know that when we go onto that international stage against the world's best, we can go there with confidence and know that if we come off, we can beat anybody," Williamson said.
After terming India as favourites, he said it is difficult to face the Asian nations, as Pakistan and Sri Lanka are also equally difficult to play.
"The obvious favourites are India, although Pakistan and Sri Lanka are also strong contenders as they are familiar with the conditions. But there are other great teams around too that will push the Indian, Pakistani and Sri Lankan sides. Twenty20 cricket is just so unpredictable, who knows on the day - anything is literally possible," he added.
Williamson, who made a nine ball duck against India on his one day international debut at Dambulla in August 2010, made his Test debut against Sri Lanka and ever since his debut, he has been an integral part of the New Zealand's playing XI (includes all the three formats).
The right handed batsman has already scored two centuries and four half centuries off 12 Test matches and in the limited overs format, he has scored tons on two occasions and made one half century off 24 matches.
