Modi, who is here to attract Japanese investment, attacked the UPA government, saying it had many internal problems and there was a possibility of Lok Sabha elections taking place earlier than 2014.
He expressed confidence that NDA would win the next elections and repeat the "good governance" witnessed during the Prime Ministership of Atal Bihari Vajpayee.
Asked directly as to what he would do for the people if he became the Prime Minister, Modi responded, "In politics, ifs and buts have no place."
His reply remained the same even when pressed further.
"What I have told you is that ifs and buts have no place in politics," he repeated.
Asked if he nurtures the ambition of becoming India's Prime Minister, Modi said, "I am committed to Gujarat. I am committed to the 60 million people of Gujarat. They have given me the responsibility. I will have to fulfil that".
