Japan’s prime minister began a two-day visit on Friday to the Philippines, where he’s expected to announce a security aid package and upcoming negotiations for a defense pact in a bid to boost Tokyo’s alliances in the face of China’s alarming assertiveness in the region.

After a red-carpet welcome at the Malacanang Palace in Manila, President Ferdinand Marcos Jr. was set to hold talks with Japanese Prime Minister Fumio Kishida on bolstering overall relations, primarily defense ties. China’s increasingly aggressive actions in the South China Sea will be high in the agenda, Philippine officials said.
