The Movement's secretary general Octo Mote last week travelled to Honiara to meet the new Solomons prime minister Rick Hou.
Rick Hou replaced Manasseh Sogavare after a vote of no-confidence, although Mr Sogavare is now deputy prime minister.
Mr Sogavare had championed the push for greater recognition of Papuan self-determination and human rights on the world stage.
After meeting Mr Hou, Mr Mote said the Solomons will continue to allocate the same level of resources to advancing the issue.
