As their boat drew closer to Subi reef, a warning signal appeared in the distance; beacon lights shone by the Chinese. The small boat's captain started to get nervous as several more warning signals were flashed and decided it was time for him and his CBS News passengers to get out of there. The team took what pictures they could through the haze, and turned back to safer shores.
At Tuesday's Ministry of Foreign Affairs briefing, China called the U.S. patrol "illegal" and "provocative."
"If we're forced to respond," said Ministry spokesman Lu Kang, "we will decide when and how to respond in our own way."
Asked by Doane whether that meant a possible military response, Lu said he would "not answer a hypothetical question."
The U.S. is expected to carry out more of the freedom of navigation patrols in what it considers international waters -- not only patrolling near Chinese outposts, but ones claimed by other countries, too.
