evidence: That’s sparked fears that if an incident escalates, it could spark a wider conflict. In the latest incident, a Chinese vessel and a Philippine supply ship collided near the disputed Spratly Islands in the South China Sea on Monday. China’s coast guard said a Philippine supply ship entered waters near the Second Thomas Shoal, a submerged reef in the Spratly Islands that’s part of territory claimed by several nations. The Philippine military called the Chinese coast guard’s report "deceptive and misleading." Here’s a look at some other incidents and developments in recent months: June 4: Philippine officials say the Chinese coast guard seized food dropped for Filipino naval personnel on an outpost on Second Thomas Shoal. Philippine Gen. Romeo Brawner says the Chinese may have suspected the packages contained construction materials intended to reinforce the rusty Philippine navy ship deliberately run aground at Second Thomas Shoal to serve as a Philippine outpost. May 16: About 100 Filipino activists on wooden boats change plans to distribute food to Filipinos based on the Second Thomas Shoal after being shadowed by Chinese coast guard ships through the night. Instead, they distribute food packs and fuel southeast of the disputed territory.
