President Donald Trump says US-China relations remain "very strong" despite the two countries being embroiled in a trade war.
Mr Trump said talks between Washington and Beijing will continue even after a deadline passed on Friday for them to reach an agreement.As a result the US raised tariffs to 25% from 10% on goods from China.
China says it "deeply regrets" the US action and would have to take "necessary counter-measures".
However Beijing also confirmed on Friday that further negotiations would take place following two days of what were described as "honest" and "constructive" talks.
The latest US move raises tariffs on $200bn (£153.7bn) worth of Chinese imports.
