China warns Canada internation summit on North Korea will only cause division

China is warning Canada that an international summit on North Korea in Vancouver next week might do more harm than good.

The Canadian government is keeping a tight lid on which countries have been invited and plan to attend Tuesday's meeting, which Foreign Affairs Minister Chrystia Freeland is organizing with U-S Secretary of State Rex Tillerson.

But a spokesman for the Chinese foreign ministry reveals that his country will not be at the table.

He says it will only create divisions and harm joint efforts to resolve the Korean peninsula nuclear issue.

Russia is also expected to be absent along with China, meaning two of North Korea's most important and influential neighbours will be missing.

A Japanese foreign ministry official, meanwhile, was quoted by Bloomberg News as raising questions about the involvement of countries such as Colombia and Greece, which are peripheral to the North Korea crisis.

Global Affairs Canada spokeswoman Amy Mills says Canada recognizes the essential role that China has to play in any diplomatic efforts involving North Korea, and has ``repeatedly engaged'' with it about the Vancouver meeting.
