North Korean leader Kim Jong Un attending a military parade in the centre of Beijing, alongside Russian president Vladimir Putin and China's leader Xi Jinping, is quite the photo-op.

It's also a key diplomatic win for Xi.

The Chinese leader has been trying hard to project Beijing's power on the international stage - not just as the world's second-largest economy, but also as a diplomatic heavyweight.

He has emphasised China's role as a stable trading partner while Trump's tariffs upended economic relationships.

Now, while a deal with Putin to end the war in Ukraine continues to elude the US President, Xi is getting ready to host him in Beijing.
