The decisive victory of Ferdinand Marcos Jr. in the Philippines' presidential election on Monday is set to re-shape the Southeast Asian country's relations with China and the United States as he seeks closer ties with Beijing.

Marcos, the son and namesake of the country's former dictator, has long-standing ties with China and is seeking a new deal with Chinese ruler Xi Jinping over contested waters of the South China Sea.

Marcos's relations with the United States, on the other hand, are complicated by a contempt of court order for his refusal to cooperate with the District Court of Hawaii, which in 1995 ordered the Marcos family to pay $2 billion (¥260.75 billion) of plundered wealth to victims of Marcos Sr.'s rule.
