The purpose of China’s Belt and Road Initiative is not to challenge US-led order

Comments on Hugh White, ANU: “China’s Belt and Road Initiative to challenge US-led order”, 9/05/2017

While there will be strategic implications as White alluded, it would still be a better world if the world cooperates rather than purely and adversely competes.
China has not deliberately excluded any countries from joining that initiative, even though some countries deliberately choose to boycott that initiative and want some others to follow them in doing that.
It is important to have an open mind as opposed to the kind of zero-sum games or even rivalries.

I would interpret China's one-belt and one road initiative as a positive contribution to the world economy inclusive of many countries, as opposed to challenging the existing US-led world order.
