The U.S. Department of Defense said on the 28th that the U.S. State Department has approved a plan to sell $8.2 billion worth of weapons equipment to Ukraine.Ukraine will purchase 3,350 ammunition missiles and supporting equipment through funds provided by Denmark, the Netherlands and Norway, as well as U.S. foreign military funding.

The British Broadcasting Corporation said on the 29th that Russia launched the second largest air strike since the outbreak of the Russia-Ukraine conflict from the evening of the 27th to the early morning of the 28th. The White House said that US President Trump was "dissatisfied but not surprised" with the current situation in Russia and Ukraine. Russia attacked Kiev, while Ukraine attacked Russian oil refineries. Neither side was "ready to end the war on its own." Trump wants to end the war, but Russian and Ukrainian leaders "must have the same will". Earlier, Trump also publicly stated that the United States will no longer directly provide financial assistance to Ukraine. If Ukraine needs weapons, it needs to obtain them through NATO's European partners. The United States only conducts arms transactions with NATO, and NATO needs to pay for the weapons in full.

Von der Leyen, the president of the European Union Commission, said on social media on the evening of the 28th that Kiev was hit by a large-scale attack, and the European Union's representative office in Ukraine was also attacked. Russian President Vladimir Putin "must sit at the negotiating table". The European Union will provide Ukraine with firm and reliable security guarantees, making Ukraine a "steel porcupine". According to the Ukrainian news agency, Ukrainian President Zelensky said in a phone call with Turkish President Erdogan on the 28th that Ukraine is ready to hold leaders-level talks to resolve the Russian-Ukrainian conflict, but Russia "avoids this form and continues the war". Zelensky said that the parties are currently "formulating each specific clause" on Ukraine's security guarantees, and "the complete plan will be completed in a written document next week".

Before the Uzbek-US delegation held a meeting in New York, Russian Presidential Press Secretary Peskov said on the 29th that Putin did not rule out the possibility of meeting with Zelensky, but full preparations should be made before any high-level meeting. Russia still shows willingness to this, but regrets that preparations for the meeting are "not active." In addition, all Russia's positions on resolving the conflict have been conveyed, and the main provisions on the settlement have been submitted to Uzbekistan in writing. Russia's "Military Observer Network" quoted analysis on the 29th that Uzbekistan and European countries are currently avoiding negotiations on specific details with Russia, but intend to put pressure on Russia through issues such as security guarantees, and accuse Russia of refusing to negotiate.

Regarding the prospects of high-level meetings between Russia and Ukraine, according to DPA, German Chancellor Merz said before meeting with French President Macron on the 28th that although Trump hopes to find a solution to the Russia-Ukraine conflict, Putin and Zelensky "obviously will not hold a meeting in the near future." German Foreign Minister Wadfour also said on the 27th that he expressed "very doubts" about any negotiations between Russia and Ukraine "in the foreseeable future." In addition, Italian Foreign Minister Tajani believed on the 28th that the Russia-Ukraine conflict "will not end soon" and "a solution will not be found before the end of this year."

According to a report by the US "Atlantic Monthly" on the 28th, US officials revealed that Trump was "frustrated" by the "unrealistic" demands put forward by Zelensky and Europe, implying that Ukraine needed to "give up part of its territory" to end the conflict. The report mentioned that Trump was reluctant to intervene further in the Russia-Ukraine conflict for fear of alienating his electoral camp. As the prospects for the Russia-Ukraine leaders 'meeting promoted by Trump become increasingly bleak, Trump is "becoming increasingly impatient." Trump "just wants it (the Russia-Ukraine conflict) to end, and it almost doesn't matter how it ends."

An article in the US magazine Foreign Affairs said that a negotiated end to the Russian-Ukrainian conflict "still seems to be a slim chance". The United States must first reach an agreement with Europe and Ukraine on security guarantees before it can prompt Zelensky and Putin to engage in talks on de facto territorial concessions to end the war. However, negotiations will be very difficult.
