Swaraj said that India had adopted a "Look East Policy" under the Atal Behari Vajpayee government.
"Now it is time to not just look but act. Under the (Narendra) Modi government, we will have an Act East Policy," the Minister said addressing a gathering of the Indian community here soon after her arrival.

"When we first talked about target 270 plus, people made fun of us. But people gave us 282 seats and with alliance we are more than 300," she said adding that the 2014 election was one of "hope".
"And hence people have lot of expectations from this government and we will not discourage them. We will live up to their dreams," she said amid rousing applause.

During her visit, Swaraj will also chair a meeting of the heads of Indian Missions in the region besides inaugurating the 3rd Roundtable of the ASEAN-India Network of Think Tanks.
