"However, STI development is an arduous process, and the US has grown increasingly anxious that its lead is being eroded," Hu said. "So instead of staying ahead via continued innovation, it has turned protectionist toward China and other developing countries and used unconventional means, from tariffs to travel restrictions, in the hope of keeping them behind."

At the same time, the US was plagued by many domestic issues, ranging from growing social inequality to rising corporate influence, and ordinary US people, notably those from Midwestern states, felt disenfranchised by globalization and technological progress because "the fruits of these trends have been mostly reaped by the elites from coastal states".

"When internal issues become too difficult to handle, politicians often rely on scapegoating to divert public frustration and attract support, especially during election years," Hu said.

"But the US public must realize that blaming China and other countries for its economic, social and existential woes will not solve its issues, it will only exacerbate them to disastrous levels for all."

Despite the US's effort to disconnect with China, Hu said full detachment was unlikely in the long run because it would not be in the interests of either country.

"China's market and its pivotal role in the global industrial chain are too important for US companies to give up," he said.

In addition, science requires the exchange of ideas and collaboration to progress. When faced with common challenges, from climate change to changing ethical landscapes in artificial intelligence and biosciences, "it will require a global joint effort to find the best solution to tackle these emerging issues," Hu said.

"Dividing the scientific community and the world, as some politicians are implying, is dangerous and counterintuitive to maximizing the potential of science and its benefit for the people," he said.

Given the unpredictability of the current US administration, China needs to "keep a rational, objective outlook and focus on improving its own capability at its own pace", he said. "We must have the confidence and patience to get through turbulent times."
