Xi Jinping and Joe Biden shake hands.
A Speedo vs 'outdated swimwear' analogy has officially entered the US-China tech war conversation.
  • Xie Feng, the Chinese ambassador to the US, said Washington isn't playing fair in its tech race with China.
  • Restrictions on China are like forcing it to wear outdated swimwear while the US wears Speedos, he said.
  • The tech war between the world's two largest economies has been intensifying.

It's no secret the US and China are locked in a strategic rivalry — from geopolitical influence to tech — but the competition is now entering bizarre territory.

We know that because a reference to Speedos, the purveyor of tight swim briefs, just got thrown into the fray.
