  • •Undersea cables are vital for global data flow and financial transactions.
  • •Countries are investing in technology to protect these cables from geopolitical threats.
  • •Tech companies are altering cable routes to minimize exposure to China.

The US-China tech rivalry is increasingly focused on undersea cables, which carry over 95% of global data. Countries like Australia, the UK, and the US are developing underwater drone technology to protect these cables. Major tech firms, including Google and Meta, are rerouting cable projects to avoid China's influence, particularly in the South China Sea. The Strait of Malacca, a critical chokepoint for maritime trade, is being bypassed in new projects to mitigate risks. This geopolitical shift may have long-lasting effects on the region's digital infrastructure and international relations. The ongoing competition is reshaping Asia’s digital landscape, with implications for security and economic ties among nations.
