China says Iran ties 'won't be interfered with' after US sanctions

China vowed Tuesday to defend its interests after the US announced plans for economic "strangulation" of Iran, a Chinese trade partner, through sanctions. Beijing stated its cooperation with Iran should not face interference. China buys nearly 90% of Iranian oil exports. US Treasury Secretary Scott Bessent declared an "economic D-Day" on Monday, targeting over 60 entities globally, including in China, to cut revenues funding Iran's nuclear and missile programs. He warned of "zero leakage" and dollar-system expulsion. Beijing insists sanctions will not resolve the war and urges a ceasefire. Iran warned that countries joining the US campaign could face "consequences," with a senior official calling such support an "act of war" and threatening a "seismic" response to Trump.
