MANILA (Reuters): Philippine President Rodrigo Duterte has stoked a feud with boxer Manny Pacquiao by criticising his "shallow" foreign policy knowledge, after the senator and eight-division champion said he found the leader's stand on the South China Sea was "lacking".

In a late night interview with SMNI news channel on Tuesday (June 8), Duterte said Pacquiao, a senator and close ally, should "study first" before weighing in.
