A decade ago, in May of 2007, when an India-Japan-US-Australia exploratory meeting was held for a similar quadrilateral dialogue, which eventually broke down after Canberra pulled out in 2008, the participants had reportedly decided to meet without a formal agenda and not to publicise the meeting or subjects that came up for discussion. All of this was reportedly done keeping in mind China's concerns over a possible attempt at its encirclement or containment.
