WASHINGTON/BEIJING, Feb 7 (Reuters) - The United States held briefings in Washington and Beijing with foreign diplomats from 40 nations about the Chinese spy balloon that entered the U.S. airspace in late January, a senior administration official and diplomats said on Tuesday. U.S. Deputy Secretary of State Wendy Sherman on Monday briefed nearly 150 foreign diplomats across 40 embassies, the official said, while in Beijing the U.S. embassy gathered foreign diplomats on Monday and Tuesday to present U.S. findings about the balloon. China's foreign ministry has said it was a weather balloon that had blown off course and accused the United States of overreacting. The State Department also sent U.S. missions around the world information about the balloon incident to share with allies and partners, the official added. Washington said the balloon was controlled by the Chinese military, the People's Liberation Army.
