MANILA - (2nd UPDATE) World leaders arrived in the country Sunday ahead of the Association of Southeast Asian Nations (ASEAN) Leaders' Summit in the capital.

Lao Prime Minister Thongloun Sisoulith was the first to land for the day at the Clark International Airport in Pampanga at 10:37 a.m.

He was welcomed by Energy Secretary Alfonso Cusi and Pampanga Governor Lilian Pineda. Hundreds of students in colorful costumes also performed a dance number for Sisoulith.

President Rodrigo Duterte met Sisoulith in the past 2 Asean summits: in Manila last April and in Vientiane, Laos last September.

Indonesian President Joko Widodo meanwhile landed in Pampanga around 12:15 p.m.

Like Duterte, Widodo has waged war against narcotics. The number of suspected drug dealers killed by Indonesian police has more than tripled so far this year from the whole of 2016, activists said.
