When will China challenge Trump?

I saw something about the US sending a carrier strike group through the south china sea last week. Here is an updated article.

It will be interesting to see if this is when China will challenge Trump, as they have done with the past two new presidents. Remember the aircraft collision in George W. Bush's first term and the incident with one of our naval survey ships under Obama?  Both were aimed at pressing a new US President. On both accounts the US didnt back down but the Chinese did gain a great deal of classified information when our reconnaissance plane conducted an emergency landing on Chinese territory in 2001.  

Personally I hope Mattis sends that carrier group within 12 nautical miles of one of the reefs China claimed and militarized. To date the US hasn't sailed within this limit publically thus adding some legitimacy to China's claims of sovereignty.
