• Quote from AWS official doc:

  The virtual private gateway is not the initiator; your customer gateway must initiate the tunnels.

• GCP VPN overview
• Azure VPN Gateway docs

Conclusions

• You can create multicloud connections between GCP, AWS and Azure using available services - AWS stays passive and awaits for connection from others
• You always need to initiate VPN connection to VGW on AWS
• Creating Cloud HUB architecture is much easier on GCP
