Myanmar's de facto leader Aung San Suu Kyi is leaving for a high-profile trip to China to discuss the fate of a jointly built dam and hydroelectric plant that Myanmar had put on hold amid questions over which country will benefit from it.

According to officials, the five-day visit starting Wednesday will tackle a new and delicate era in relations, including development aid and Myanmar's upcoming complex peace process involving the government, the military and ethnic armed groups.

It is Suu Kyi's first visit to Beijing since her National League for Democracy party took office in March.

The former military-backed government of President Thein Sein suspended work on the Myitsone Dam in northern Myanmar in 2012, because 90 percent of electricity would benefit China.
