Manila recently allowed a Chinese ship to conduct maritime research at a resource-rich vast underwater plateau known as Benham Rise, east of the main island of Luzon, near US bases in Guam and Hawaii.
For months, the Philippines has been drumming up a joint venture with China to explore for oil and gas in a contested area of the South China Sea.
China is also dipping its fingers into the Philippine telecoms industry. Shenzhen-based telco ZTE is leading a consortium that plans to invest US$2 billion (S$2.6 billion) to build 50,000 microcell towers and compete with the two leading players.
Most big-ticket infrastructure projects have some level of Chinese involvement.
Tourists from China are also pouring in. The Chinese have dislodged the Koreans as the top tourists on the resort island of Boracay. Some 376,000 tourists from the mainland visited Boracay last year, compared with 375,000 from South Korea.
A historic ruling by an international tribunal in The Hague granting the Philippines rights to vast waters China is claiming, meanwhile, is fast slipping out of the national consciousness.
