Kiev [Ukraine], The Biden administration will send $2 billion in additional military aid to Ukraine amid the ongoing conflict with Russia, US Secretary of State Antony Blinken said at the conclusion of his two-day visit to Kiev on Wednesday (local time) . To highlight Washington's support, the Washington Post reported. Blinken said the US$2 billion would come in the form of a "first-of-its-kind Defense Enterprise Fund" that will provide assistance to Ukraine in the coming months. The aid, in the form of new weapons systems and support for Ukraine's defense industry, comes partly from a US$61 billion package that the US Congress approved last month, while US$400 million is earmarked for general foreign defense assistance. Comes from a different pool of money. , which is now being directed towards Ukraine.However, Blinken also stressed that the Biden administration opposes Ukraine attacking targets inside Russian territory with American weapons – a point Ukrainian policymakers are increasingly emphasizing. The visit coincided with Russian military advances that exposed Ukraine's security in an "extremely weak" light. Russia has in recent days attacked towns near Kharkiv, Ukraine's second-largest city. Ukrainian President Volodymyr Zelensky canceled a planned visit to Spain on Wednesday as concerns grew about the latest Russian attacks. “We have not encouraged or enabled attacks outside Ukraine,” Blinken told reporters Wednesday at the end of his first visit to Ukraine since September.Blinken added, "But ultimately, Ukraine has to make its own decisions about how it will conduct this war, a war it is waging to defend its independence, its sovereignty, its territorial integrity." “And we will continue to support Ukraine with the tools it needs to succeed. In particular, Ukraine is able to use weapons supplied by other countries, including the United Kingdom, to hit targets on Russian soil, with the White House restricting American equipment. Attacking Russian territory out of fear of provoking a direct military conflict with Russia has proven 'frustrating' for Ukraine, particularly in recent weeks, as I reported military strikes on Russian territory close to Kharkiv, Washington Post reports. Have seen the gathering. Ukraine's Foreign Minister Dmytro Kuleba found its ability to attack it very limited, the report said, appreciating the US help, but he criticized 'congressional inaction' for more than six months before the April approval. Reason also acknowledged the "difficulties" faced by Kiev.About help. "Every delay in supplies results in a blow to the front line. This is the general rule," Kuleba said. “When a Ukrainian infantryman or gunner has everything he needs, we are winning. Every time there are supply delays and inadequate supplies, we are not winning.The law of war is true but very clear." The report cited analysts and U.S. officials as saying that Russian forces do not appear ready to capture the city of Kharkiv, but they may be moving there to pull out Ukrainian military assets. The Institute for the Study of War, a Washington-based independent research group, said Russia's attack on the north-east Kharkiv area has slowed, indicating it is likely creating a buffer. There was no attempt to capture the city, the Washington Post reported, adding that Russia had continued to make small but steady gains in the south.
