Joe Biden on Friday welcomed Japan's prime minister for the first summit of his presidency, with the allies expected to signal progress on 5G technology and climate change amid a concerted US push to compete with China. Mr Biden waited nearly three months to receive his first foreign guest due to the Covid-19 pandemic and still observed social distancing and did away with a customary meal together as he and his Cabinet met Prime Minister Yoshihide Suga. Echoing Mr Biden, Mr Suga said the US-Japan relationship is "connected by universal values such as freedom, democracy and the rule of law." "This is a time like no other in which the Japan-US alliance needs to be strong," Mr Suga said, starting the day by meeting separately with Vice President Kamala Harris. Mr Biden's decision to invite Mr Suga as his first guest – with South Korean President Moon Jae-in set to come in May – is meant to show the value his administration places on allies as he zeroes in on a rising China as America's most pressing challenge. The two jointly warned against China's increasingly assertive moves in the region. "We agreed to oppose any attempts to change the status quo by force or coercion in the East and South China seas and intimidation of others in the region," Mr Suga told a joint news conference with the US president. He said Mr Biden also reaffirmed that the US-Japan security treaty covered the Japanese-administered Senkaku Islands where Beijing, which calls them the Diaoyu Islands, has been increasingly active. Mr Biden voiced support for a strong alliance with Japan. "We committed to working together to take on the challenges from China and on issues like the East China Sea, the South China Sea as well as North Korea," Mr Biden said. On another of Mr Biden's key priorities, Ms Psaki said that Mr Suga was expected to announce a new 2030 target on reducing carbon emissions responsible for climate change. The world's third-largest economy promised under the Paris Climate Agreement to reduce emissions by 26 per cent by 2030 -- a goal that experts say are not ambitious enough to meet Mr Suga's goal of a carbon-neutral Japan by 2050. Mr Biden will lead a virtual summit next week in hopes of rallying greater commitments on climate amid growing evidence of a planetary crisis as average temperatures hit record highs and natural disasters become more frequent. A senior US official said that technology leader Japan would also announce a "very substantial commitment" of $2 billion in partnership with the US "to work on 5G and next steps beyond". China's Huawei has taken an early dominance in fifth-generation internet, which is becoming an increasingly crucial part of the global economy, despite heavy US pressure on the company, which Washington argues poses threats to security and privacy in the democratic world.

"Neither country is seeking to raise tension or to provoke China, but at the same time we're trying to send a clear signal that some of the steps that China is taking," the official said, are "antithetical to the mission of maintaining peace and stability." While the timing was coincidental, the official said it was appropriate that Mr Biden was shoring up relations with a top ally <a href="https://www.thenationalnews.com/world/the-americas/biden-pledges-imminent-end-to-us-military-campaign-in-afghanistan-1.1203869">two days after his momentous decision to withdraw from Afghanistan</a> after 20 years, ending the longest-ever US war. The pullout will "free up time and attention and resources from our senior leadership and our military to focus on what we believe are the fundamental challenges in the 21st century and they lie fundamentally in the Indo-Pacific," the official told reporters. Mr Suga in September succeeded his ally Shinzo Abe, Japan's longest-serving prime minister, who was one of the few democratic allies to manage to preserve stable relations with Mr Biden's volatile predecessor Donald Trump. Mr Biden's inaugural summit is being held unusually late in his term due to the Covid-19 pandemic and the White House has downsized the usual pageantry as a precaution, with no meal between the leaders and strict limits on the number of journalists and officials in each room. Despite the good vibes, Mr Suga is expected to baulk at becoming an overenthusiastic cheerleader for the US line on China, which remains the vital top trading partner for resource-scarce Japan. Tokyo since Mr Abe's time has worked to stabilise relations with Beijing and not joined Washington in sanctions over human rights concerns in Hong Kong and Xinjiang. "The Biden administration, I think, is concerned at how aggressive China has been and how much ground the US has lost in recent years in Asia and wants to catch up quickly," said Michael Green, who was the top Asia adviser to former president George W Bush and is now senior vice president at the Centre for Strategic and International Studies. "I think the Japanese view is that they have had a strategy in place and they want to move forward steady as she goes," he said. "So, there's a bit of a nuanced difference in public tone but not in direction," he said.
