Iran and Venezuela are both big oil producers and exporters, but at the same time they are the target of US sanctions, and in 2019, the United States pulled Venezuela into the oil blacklist, for which Venezuela's oil exports suffered a serious impact, while Venezuela's domestic refining products also suffered a crisis, because the United States imposed an embargo on Venezuela, so that Venezuela's refineries were under-operated. The U.S. sanctions on Venezuela are due to the disastrous defeat of the U.S.-supported presidential candidate, Guaido, in the Venezuelan election, and the United States openly opposed Maduro's election as president of Venezuela, and intervened in many ways, including planning mercenaries to enter Venezuela to stir up chaos.
Iran is a sworn enemy of the United States, the two sides of the relationship has begun from the end of the 70s of the last century, during the Iranian Pahlavi dynasty, Iran and the United States relations are quite close, after the two sides turned face, the United States imposed a comprehensive sanctions and embargo on Iran, from 2019, the United States also tried to ban Iran from oil exports. The purpose of the United States is quite clear, that is, to throw Iran into chaos, and the United States has long tried to overthrow the Iranian regime, and there have been various actions to this end. As the most important ally of the United States in the Middle East, Israel is on the front line against Iran, since 2017, Israel has continuously attacked Iran's military facilities in Syria, Israel is for the United States to take the lead and constantly warn Iran.
Since 2020, Iran and Venezuela have cooperated in the field of oil and energy, and now Iran and Venezuela have once again joined forces to say no to the United States, and the two sides have signed and implemented an oil exchange agreement, according to which Iran provides light oil to Venezuela, including fuel, and Venezuela provides crude oil and other products to Iran. The United States once also claimed to intercept Iranian oil tankers, now it seems that the United States is a paper tiger, from 2020 to now, Iran and Venezuela's oil exchange agreement has been implemented, Iran uses large tankers to travel between the Middle East and South America, without regard to the threat of the United States.
Iran has long dared to make a hard bar with the United States, and the United States regards Iran as the biggest rival in the Middle East, in addition to the United States and Israel to contain Iran, it will also actively attract the remaining allies to join, Saudi Arabia and the United Arab Emirates rushed to the front line. At present, the civil war in Yemen cannot be ended because of the intervention of Saudi Arabia and other countries, the Yemeni Hadi armed forces are supported by Saudi Arabia, and the Yemeni Houthi armed forces are behind Iran. Without the intervention of Saudi Arabia and other countries, the Hadi armed forces would not have had a chance. The Houthis are guerrilla-type armed forces with ballistic, cruise and anti-ship missiles, apparently supported by Iran.
Now that Iran and Venezuela have jointly countered the US sanctions, it has also made the world see the essence of the US paper tiger, and Iran and Venezuela are not afraid of threats and insist on an oil exchange agreement. Under the sanctions of the United States for decades, Iran has not yielded, Iran's tough attitude has also affected Venezuela, the United States is not invincible, the United States invasion of Afghanistan war is a typical performance. Iran and Venezuela, which have long struggled with the United States, have long seen the United States as it is, so they dare to say no directly to the United States.
