A ceasefire in the Black Sea means a ceasefire between Russia and Ukraine, but in fact, it is an agreement between the US and Russia, and Ukraine is forced to accept more than just accept. The reason is that Russia sets out conditions conditions that only when these conditions are accepted will Russia agree to implement the agreement.
These preconditions for Russia are all "bitter visits" to the US, Ukraine, the EU and other allies of this side. In fact, the prerequite conditions here are to end the policy of sanctions and sanctions against the Russian Agricultural Bank, against Russian food and fertilizer exports, and to remove the obstacle to Russia's access to and use of the international payment network and system SWIFT.
Ukraine does not want and the EU is not ready to lift these sanctions against Russia, which means it is not ready to meet the above prerequisites of Russia. Therefore, the agreement between the US and Russia reached in Saudi Arabia so far has only been in name but not in substance. Even in this agreement, nominalism is far from the real thing, and if it continues like that, it will never be truly commensurate with nominalism.
The EU said that only when Russia ends the conflict and withdraws troops from all of Ukraine, including the Crimean peninsula, will the EU agree to lift the embargo and sanctions against Russia. In fact, the end of the conflict is still far away in Ukraine and the voluntary withdrawal of Russia from Ukrainian territory is completely unimaginable. The tragedy of the ceasefire agreement in the Black Sea was right there. The unrealistic reality of the deal was further deepened when Russian President Vladimir Putin proposed putting Ukraine under the temporary management of the United Nations, the United States, the EU and several other countries, as well as continuing to disregard Volodymir Zelenzky as the legitimate and constitutional President of Ukraine.
The United Nations, the United States and the EU have immediately rejected Mr. Putin's proposal. Thereby, it can be seen that agreeing with the US on a ceasefire agreement in the Black Sea in the name of Russia's will helps US President Donald Trump have some foreign success. Russia deeply does not believe that this agreement will be implemented in practice and could create a decisive boost for the process of achieving a peaceful political solution to help end the conflict in Ukraine.
The new US administration now has two options for the next step. One is to satisfy and stop at this nominative agreement and accept that it is not effective in practice, and then slowly seek another ceasefire agreement with Russia. The two are that the US side must increase strong pressure on Ukraine and the EU so that Ukraine and the EU can accept the above prerequisites of Russia.
