Suu Kyi's National League for Democracy party sailed through the two-thirds majority it needs to rule, claiming 348 parliamentary seats with a number of results yet to be declared.
Myanmar's pro-democracy leader Nobel laureate Aung San Suu Kyi won a seat in the country's lower house of parliament on Sunday after defeating her two rival candidates in a by-election in her constituency, the main opposition party said.
Nobel Peace Prize winner Suu Kyi has been criticised for failing to do enough to prevent the violence.
Swaraj also called on Myanmar President U Htin Kyaw and held discussions with him on issues of mutual interest.
