Boris Johnson’s plan to host an expanded Group of Seven summit in June is worrying some other members who fear the U.K. may be trying to reshape the forum of wealthy nations via the back door.

The British prime minister has invited South Korea, India and Australia as guests to this year’s meeting as he tries to establish a so-called D-10 coalition of democracies to counter China and other authoritarian states. Johnson wants to champion global action and democratic values, and project the U.K. as a force for good after leaving the European Union.

While it is standard practice for a G-7 host to invite more countries to the summit, the involvement of guest nations is typically limited. According to a person familiar with Johnson’s plans, that will change this year with the three countries set to take part from the get-go, from preparatory meetings of the leaders’ diplomatic emissaries early next month through to ministerial gatherings before the summit.

Though diplomats are waiting to understand the full implications, there’s some concern Johnson’s D-10 is a step toward restructuring the G-7.

One diplomat said a rival grouping risks weakening the G-7, and that could eventually raise pressure on it to expand in order to regain its lost influence. Expansion is an idea Italy, Germany, France and Japan oppose, according to officials familiar with those governments’ positions.

China Risk

Two European diplomats also warned there’s a risk that anti-China rhetoric foments a Cold War-style standoff with Beijing, which both said the G-7 must avoid after it batted away Donald Trump’s attempts to do the same.

“We reject any cliques or group politics under the pretext of multilateralism,” China Foreign Ministry Spokeswoman Hua Chunying said at a press conference in Beijing on Tuesday. “We oppose using the pretext of multilateralism to impose rules determined by a few countries onto the international community.”

One diplomat said there would also be doubts within the group about whether a U.K. idea established for domestic reasons would have any staying power. The U.K. government didn’t respond to a request for comment.

The issue of expanding the G-7 cuts to the heart of questions about the future of the forum and where members’ strategic interests lie, especially on China.

Post-Trump

This year’s summit is a chance to repair ties after years of splintering in the Trump era. The outgoing U.S. president refused to sign the end-of-summit communique in Canada in 2018, while last year’s meeting—which Trump was meant to host—never took place.

Johnson intends to put issues including climate change, which was undermined by Trump, at the center of this year’s summit along with trade, health, press and religious freedoms, and human rights.

According to diplomats, the club’s other six members welcome those aspirations, and also want to cooperate on the post-pandemic recovery.

The U.K. has also assured members it has no plans to propose changes to the G-7 format and it will remain distinct from the wider group of democracies, according to three diplomats familiar with the matter. That hasn’t fully assuaged G-7 members’ concerns.

Expansion

One of the diplomats said while there is no immediate prospect of extending the group, once institutionalized the D-10 could compete with the G-7 for relevance. Another said the U.K. must consult closely with G-7 members about its plans for the D-10 coalition.

Another official said some of those concerns are shared but that the full extent of the guests’ role is not clear, and the three countries would not participate in all the preparatory work. The same official also pointed out that expanding the G-7 would require unanimity, making it unlikely anytime soon.

The debate over reformatting the G-7 isn’t new, and the expansion idea was floated by Trump last year. In addition to Australia, South Korea and India, he proposed re-inviting Russia, which was ejected after the annexation of Crimea.

President-elect Joe Biden hasn’t indicated where he stands on the issue but has said he wants to convene a summit of democracies once in office.

Doubts

Some experts question the effectiveness of the concept given countries such as China are simultaneously perceived as a geopolitical threat while being a key partner on issues such as climate change.

Both the D-10 and Biden’s summit of democracies are distractions that are likely to get stuck on questions of definition and inclusion criteria, obstructing their intended aim to develop guidelines on how to deal with authoritarian states, according to Constanze Stelzenmuller, Fritz Stern Chair on Germany and trans-Atlantic Relations at the Brookings Institution.

“For example, Hungary, Russia or China are obviously never going to be included in a D-10,” Stelzenmuller said. “But with the current Polish or Indian governments you are already entering a gray zone.”

Still, prominent voices on both sides of the Atlantic continue to push for the Group of Seven to open its doors to new members.

‘Rule of Law’

Tobias Ellwood, chairman of the House of Commons defense committee, said this month an expanded G-7 including Australia, India and South Korea “can begin to address and reverse the demise in global stability, democratic values and rule of law.”

Johnson’s agenda has potential sticking points beyond the expansion debate. South Korea’s participation is awkward for Japan given renewed tensions stemming from its 1910-1945 colonial rule over the Korean Peninsula.

U.K. and European diplomats also point to geopolitical differences. A British diplomat said that having left the EU, it makes economic sense to improve ties with Asia-Pacific nations, including those in the 10-member Association of Southeast Asian Nations, with whom the U.K. is seeking a partnership status and which is also expected to be invited to the G-7 leaders’ summit.

It should also be seen in the context of a more robust approach toward China compared with that of the EU, the diplomat said. Since decoupling from the bloc’s trade policy, Britain has been more outspoken on China and Hong Kong.

Meanwhile the EU has faced criticism, including from the incoming Biden administration, for agreeing a trade deal with Beijing. Officials in Brussels and some European capitals argue trade should be kept separate from issues that can be dealt with using other tools, such as sanctions.

Two European diplomats said the narrow focus on the Asia-Pacific region relegates areas of strategic interest to Europe, including Africa, and ignores regions like Latin America.
