Metro Manila (CNN Philippines) — Filipinos have poor trust in China, their country’s principal rival over territories in the South China Sea, according to a recent survey by the Social Weather Stations (SWS).

The June 24-27 poll results released Monday by the SWS showed 51 percent of Filipinos have "little trust" and 27 percent have "much trust" in China, while 19 percent were undecided. This garnered China a net trust rating of -24 percent, which is classified as “poor” by the independent pollster.

The net trust rating is the difference between those who have “little” and those who “much” trust in China. A net rating of +70 percent and above in a public trust survey is classified as “excellent” while a +9 percent to -9 percent is considered “neutral” while a -10 percent to -29 percent is “poor,” according to SWS standards.

The survey, which polled 1,200 adults nationwide and has a margin of error of ±3 percentage points, was conducted about two weeks before the Arbitral Tribunal in The Hague ruled on July 12 in favor of the Philippines against China. The ruling junked China’s “nine-dash line” claim over most of the South China Sea.
