Venezuelan leader Nicolas Maduro prepared to rally his military supporters Thursday as the US and key allies backed a challenge from his leading rival who declared himself "acting president."
US President Donald Trump declared Maduro "illegitimate" and called the National Assembly legislature "the only legitimate branch of government."
Maduro's key financial backer China also weighed. Foreign ministry spokeswoman Hua Chunying said China opposes "interference" in Venezuelan affairs and called for a "political resolution."
He condemned what he called the US leader's "extremist policy" as "a very serious folly."
"Trying to impose a government by extra-constitutional means, we cannot accept that."
