The hottest topic recently is the "kill line" discussion.

I won't debate whether the US or China has a lower kill line,
but I welcome such heated debates.

As G2 competitors,
China and the US should not only compete in military, technology, economy, and trade,
but also in the overall welfare and social security of their citizens.
Both sides should supervise each other, expose shortcomings, and reveal flaws,
forcing each other to continuously improve.
This is the true meaning of great power competition!
