China warns the US and Japan over Taiwan and offers talks with Lithuania

China has issued a series of warnings and diplomatic moves centered on Taiwan. It warned the United States that arms sales to Taiwan could threaten a planned visit by Trump in April, and it urged Japan's prime minister to retract recent remarks about the island. In a separate development, China signaled it is open to restoring diplomatic ties with Lithuania after the Lithuanian prime minister called the opening of a Taiwan office 'a mistake'.
