Donald Trump has rejected suggestions that the warming of relations between China, Russia and their allies poses a challenge to the US on the global stage.

The US president told reporters in the Oval Office that he had "a good relationship" with President Xi Jinping and that China "needs us more than we need them".

It comes as Xi prepares to host world leaders at a "Victory Day" parade in Beijing on Wednesday - a showcase of China's military might.

Xi will be joined by North Korea's Kim Jong Un and Russia's Vladimir Putin, viewed by some observers as a message to the Western nations that have shunned them.

China has sought to position itself as a possible counterweight to the US since Trump's tariffs rocked the global economic and political order.

Trump has pitched his tariffs as essential to protecting American interests and industry. It appears that any diplomatic cost is something he is willing to pay.

Asked by the BBC if he believed Beijing and its allies were attempting to form an international coalition to oppose the US, Trump said: "No. Not at all. China needs us."

He added: "I have a very good relationship with President Xi, as you know. But China needs us much more than we need them. I don't see that at all."

Separately, in a radio interview on Tuesday, Trump said he was not concerned about the axis forming between Russia and China.

He told the Scott Jennings radio show that America has "the most powerful military forces in the world" and that "they would never use their military forces against us".

"Believe me, that would be the worst thing they could ever do," he said.

Elsewhere in the interview, Trump said he was "very disappointed" in Putin, after they failed to reach a peace deal for Ukraine during their meeting in Alaska last month.

"I'm very disappointed in President Putin, I can say that," Trump said, adding that the US "will be doing something to help people live" in Ukraine. He did not specify.

China has not criticised Putin's full-scale invasion and has been accused by the West of aiding Russia's war effort through its supply of dual-use materials and purchases of Russian oil. Beijing denies this.

Meanwhile, Ukrainian President Volodymyr Zelensky said Russia was engaged in a new troop build up along certain sectors of the frontline.

"[Putin] refuses to be forced into peace," Zelensky said in his nightly video address.

A US congressional panel has released a trove of documents related to the federal investigation into the late sex offender Jeffrey Epstein.

The House of Representatives Oversight Committee published 33,295 pages, including flight logs, jail surveillance video, court filings, audio recordings and emails.

But Republicans and Democrats alike said the files contained little new information and it is unclear if the justice department is withholding other Epstein records.

Pressure has been growing from President Donald Trump's own supporters for more transparency on the probe into the well-connected financier after the justice department said in July there was no "incriminating" Epstein client list.

Oversight Committee Chairman James Comer, a Republican, ordered the documents to be published online on Tuesday.

The Republican-led panel received the files after issuing a legal summons to the Department of Justice last month.

But Comer, a Kentucky congressman, acknowledged there was little fresh information.

"As far as I can see, there's nothing new in the documents," he told NBC News.

The videos released on Tuesday include footage from outside Epstein's New York jail cell on the night of his death.

It includes 13 hours and 41 seconds of video from the facility covering the evening of 9 August to the morning of 10 August 2019, when Epstein died.

This is two hours more of video than what the justice department released two months ago.

But the newly released footage does not include the so-called "missing minute" - a jump in the timecode between 23:00 and 00:00, according to the BBC's US partner CBS.

Attorney General Pam Bondi previously said the "missing minute" was just the jail's camera system resetting each night.

However, the apparent anomaly had stoked conspiracy theories about the official finding that Epstein died by suicide.

The convicted paedophile had once hobnobbed with the likes of Trump, former President Bill Clinton and British royal Prince Andrew.

The tranche of documents also includes several clips from 2006 showing interviews with people who said they were victims of Epstein.

Their faces are blurred and names removed from the audio as they talk about alleged sexual abuse while they were hired for massages.

Other videos show bodycam footage from police in Palm Beach, Florida, as they search a home belonging to Epstein.

Some of the documents date back 20 years, covering an initial criminal investigation into Epstein launched by Palm Beach police.

But Robert Garcia, the top Democrat on House Oversight Committee, said in a statement: "To the American people – don't let this fool you.

"After careful review, Oversight Democrats have found that 97% of the documents received from the Department of Justice were already public.

"There is no mention of any client list or anything that improves transparency or justice for victims."

Democratic congresswoman Summer Lee said the "only new disclosure" was flight logs taken by US Customs and Border Protection, which show Epstein's travel to and from his private island in the US Virgin Islands.

The release came after backbench Republican rebel Thomas Massie forged ahead on Tuesday with a bipartisan effort to force the House to vote on a bill requiring the justice department to publish all of its Epstein files within 30 days.

The Kentucky congressman said: "People want these files released. I mean, look, it's not the biggest issue in the country.

"It's taxes, jobs, the economy, those are always the big issues. But you really can't solve any of that if this place is corrupt."

Earlier on Tuesday, House Speaker Mike Johnson, a Republican, and members of the oversight committee met six Epstein victims behind closed-doors.

Johnson, a Trump ally, told reporters afterwards that "there were tears in the room" as they heard from the Epstein victims.

Congresswoman Nancy Mace, a South Carolina Republican, appeared to leave the meeting crying.

Democrat Melanie Stansbury praised the survivors for speaking out and described the case as a "cover-up of epic proportions".

Lawmakers and victims of Epstein plan to hold a news conference on Capitol Hill on Wednesday.
