China will block iPhone sales and order planes from Airbus rather than American firm Boeing if Donald Trump starts a trade war, according to reports.
Mr Trump has previously claimed he would put a 45% tariff on American exports, and called China a "currency manipulator."
However the country's state-run Global Times newspaper said Trump would be "naive" to start a trade war and they would respond with "counter-measures" if tariffs rise.
The newspaper said: "A batch of Boeing claims will be replaced by Airbus. US auto and iPhone sales in China will suffer a setback, and US soybean and maize imports will be halted. China can also limit the number of Chinese students studying in the US.
"Finally the new president will be condemned for his recklessness, ignorance and incompetence."
Despite this, the Chinese president Xi Jinping is said to have spoken to Trump, agreeing that cooperation is the way forward.
Trump added that there is a “clear sense of mutual respect," between the two.
