Russian President Vladimir Putin delivered a foreign policy speech showing no sign of ending the full-scale invasion of Ukraine, with analysts noting all indications point to continued war.

The twin developments come amid ongoing US-brokered peace talks between Russia and Ukraine, raising doubts about the prospects for a negotiated end to the nearly four-year conflict as Moscow continues large-scale strikes.
