The national flags of China and the United States [Photo/Xinhua] To debunk some US politicians' preference to blame China for miscellaneous problems in the United States, a senior Chinese diplomat has said that "to destabilize China is by no means a solution to the US' problems". "For a superpower like the US, the biggest challenge is always itself," Vice-Minister of Foreign Affairs Le Yucheng said in an interview with Chinese news portal guancha.com published on Saturday, covering a wide range of topics related to the world's two largest economies. "We have no strategy for seeking hegemony but for our own development, and our goal is to realize the people's aspiration for a better life," Le said.
