The only US president to complete his term without war, military attack or occupation has called the United States "the most warlike nation in the history of the world."

During his regular Sunday school lesson at Maranatha Baptist Church in his hometown of Plains, Georgia, Jimmy Carter revealed that he had recently spoken with President Donald Trump about China. Carter, 94, said Trump was worried about China's growing economy and expressed concern that "China is getting ahead of us."

Carter, who normalized diplomatic relations between Washington and Beijing in 1979, said he told Trump that much of China's success was due to its peaceful foreign policy.

"Since 1979, do you know how many times China has been at war with anybody?" Carter asked. "None, and we have stayed at war." While it is true that China's last major war – an invasion of Vietnam – occurred in 1979, its People's Liberation Army pounded border regions of Vietnam with artillery and its navy battled its Vietnamese counterpart in the 1980s. Since then, however, China has been at peace with its neighbors and the world.
