“(Tillerson) express concerns over the violence and insecurity affecting the Rohingya and other local populations and discuss ways to help (Myanmar) end the crisis and chart a productive way forward,” a State Department spokesperson told reporters in Manila on Tuesday.
In Manila, Suu Kyi also met with UN Secretary-General Antonio Guterres, who demanded a guaranteed access of humanitarian aid in Rakhine and the safe and voluntary return of refugees who have fled to Bangladesh since the conflict broke out on August 25.
More than 618,000 people have fled to the neighbouring Bangladesh after the army launched an offensive in the north of the western Rakhine State in response to the attacks by a group of Rohingya insurgents on security posts in late August.
The US lifted sanctions against Myanmar after the last military junta dissolved and transferred the power to a civilian government, which was made up of former generals who initiated a process of democratic reforms in 2011.
Suu Kyi took up the reins of the government in 2016 after her party National League for Democracy won a landslide victory, the first free elections in the country after half a century of military regime.
