"China continued building military and civilian infrastructure on the 3,200 acres of artificial islands it has created since 2013, completing runways and building reinforced aircraft hangars on three outposts," the report stated on Wednesday.
The latest projects will improve China’s ability to detect and track foreign maritime forces and fishing boats passing through the South China Sea, an international waterway used by nearly half of the world’s commercial shipping, the report explained.
The report also noted Chinese tests of new space launch vehicles and launches of additional intelligence, surveillance, reconnaissance and navigation satellites in 2016.
In addition, the report explained that since late 2015, China has participated in 11 major bilateral or multilateral exercises with other nations.
The Commission was established by the US Congress in 2000 to assess Chinese economic and military developments in reports for lawmakers, government officials and private industry.
