Quad's commitment to provide a billion vaccines to people in Southeast Asia is on track: White House official

"Our discussions with both our partners in the private sector and also in government suggests that we are knock-on-wood still on track for 2022,” he said.

Participating in a panel discussion organised by the Center for New American Security, a think-tank in Washington DC, the top White House official said that the most intense efforts right now really are in the short-term.

“I think we''re feeling relatively confident as we head into 2022, but we recognise that what we are facing right now across Asia, in fact, across the world are new strains that spread more rapidly,” Campbell said.

So even countries that did extremely well through social distancing and masking are now facing outbreaks even with tremendous stringency, he said.

“So, we understand the only way to be effective to counter this is through vaccine diplomacy. We are trying to step that up more generally,” Campbell said.

Campbell said that the goal is to hold an in-person Quad meeting and a “very ambitious meeting” here in Washington, in the fall, he said.

“With all leaders in attendance, we will ensure that we''ve taken the necessary steps on the vaccine deliverable,” Campbell said.

“We intend to build on that. We want to do something constructive with respect to infrastructure. We are going to take some other steps to build out the Quad to ensure that as an unofficial gathering, it still is a defining feature of modern diplomacy linking these key maritime democracies in a way that is deeply consequential for the 21st century,” he said.

Responding to a question on news reports of expansion of the Quad, he said that the focus is going to be on deepening and increasing familiarity and broaden within governments.

“We recognize that our strategic purpose extends beyond vaccines. We''re going to look at a number of areas where we think there are some natural arenas for cooperation. This is not a closed architecture. I think we want others to participate with us subsequently and follow through on initiatives,” he said.

"We are briefing people actively on it. I will say that we are getting interest. People want to learn more,” Campbell said.

They want to understand how they can be actively engaged, he said.

“We think that''s a positive sign. We are focused on really now more than anything else, however, is make sure these foundational members take the necessary steps to support a strong venture,” Campbell said.
