Defense officials told CNN that a formal diplomatic protests known as a démarche is expected to be issued.
The Pentagon has repeatedly said that China represents an increasingly serious threat to regional security, saying that major Chinese investments in its military are aimed at achieving regional dominance.

The US has similarly issued such diplomatic protests in the past due to what the US said was Chinese military forces using lasers against US aircraft.
