Hungary's Prime Minister Viktor Orban will discuss U.S. sanctions on Russian oil companies among other issues when he meets U.S. President Donald Trump in Washington next week, Foreign Minister Peter Szijjarto said on Monday.

"Eventually the administration decided it's not enough to just use carrots to pressure Putin, you also need sticks," one analyst said.

Days after canceling a planned summit with Putin, citing a lack of progress toward ending the war in Ukraine, Trump took a major step by effectively blacklisting Rosneft and Lukoil.

The U.S. sanctioned the Colombian president, an escalation of the feud between President Trump and the South American leader.

The Trump administration has imposed sanctions on Colombian President Gustavo Petro, his family, and a government member over drug trade allegations.

It is increasingly difficult for Putin to finance his war. Every Euro we deny Russia is one it cannot spend on war."

China's commerce ministry on Monday vowed to "resolutely safeguard legitimate rights and interests of Chinese companies" after the UK imposed Russia-related sanctions on 11 Chinese firms earlier in October.

The US Congress is yet to fully repeal sanctions, stifling foreign investment. Much of Assad’s kleptocratic bureaucracy and labyrinthine laws remain in place. And the vast majority of Sharaa’s MOUs (memorandum of understanding) are yet to materialise into actual deals.

The US has placed sanctions on Colombia's President, Gustavo Petro, accusing him of failing to curb drug trafficking and allowing cartels to "flourish". The decision is the latest in a growing diplomatic dispute between the Latin American nation's first left-wing leader and his US counterpart Donald Trump.

Trump said Petro “has allowed drug cartels to flourish,” describing the move as part of his administration’s effort to block narcotics from entering the United States.

U.S. President Donald Trump's administration has prepared additional sanctions it could use to target key areas of Russia's economy if President Vladimir Putin continues to delay ending Moscow's war in Ukraine,
