Japanese Foreign Minister Fumio Kishida said Friday he will hold formal talks with his Chinese counterpart Wang Yi in a last-ditch effort to open up an opportunity for the two countries' top leaders to have a constructive dialogue early next week on the margins of a regional economic summit.

Japan and China have not held official foreign ministerial talks since September 2012.

Kishida told reporters it is still undecided when the official meeting with Wang will be held.
