At a Senate committee hearing on Tuesday, the United States said it expects to retain some sanctions on Iran's economy, including those imposed under President Donald Trump, even if it reinstates parts of its previous deal with Iran. US media say hundreds more sanctions could be imposed on Iran's economy.

Remember, in the second half of 2020, the United States imposed sanctions on more than 700 Iranian entities and persons almost every week. In the wake of the hearing comments, with talks now looking more elusive and U.S. negotiators making increasingly cautious statements in Vienna about reaching a deal, oil prices continued to climb this week, after U.S. crude futures hit a 2-1/2 year high earlier this month. US oil prices have touched $70 a barrel in recent days and Goldman Sachs expects prices to hit $80 this summer, assuming no breakthrough in the Vienna talks.

This latest turn of events is another sign of the uncertainty in the global oil market. But there are signs that the Iranian economy has grown sufficiently resilient to sanctions and restrictions from the United States. Another new change is, according to the Russian satellite news agency quoted the us department of energy, according to the United States from Iran's oil imports for the first time in March this year, an average of 1 million barrels per month, if the data is correct, it is also the first time after the United States more than 30 crude oil imports from Iran, but quite ponder, Iran's oil ministry spokesman said in the following, "Iran does not have data on U.S. imports of Iranian oil," he said. "We have no official information on that and we cannot confirm it."

But it is worth mentioning that, according to the Russian media and follow up the Associated Press reported, the United States, according to the judicial documents in February this year, the United States in the united Arab emirates oil tanker seized a ship off the coast of Iran, its carrying about 2 million barrels of oil have been sold in the United States, profit of $110 million (total about 700 million yuan), and the time and the U.S. department of energy (doe) data released on May 30, close to, Later, the spokesman noted that "this is an interesting and unreasonable question, given that the United States itself is currently imposing economic sanctions on Iran," at a time when the United States had also announced that it would cut its oil imports from Iran to zero and called on other countries not to buy Iranian oil.

Iranian media a week ago quoted Iran's chief vice president as saying that the United States forced SWIFT to cut off access to Iran's central bank, leaving overseas customers unable to trade, reversing Iran's oil industry. In the 18 months ending in April, Iran's oil exports fell by 80 percent to 2.614 million barrels per day. Combined with the fact that the U.S. imported Iranian crude oil in March, the Iranian economy may in some ways have broken some of the shackles of the U.S. and the dollar.

In response, Iran's central bank governor said recently that his country had also won a legal battle in Luxembourg to block a U.S. attempt to seize $1.6 billion in Iranian funds. In January, Iran said its lawyers in Italy had also successfully blocked a U.S. attempt to seize $1.7 billion of Iranian assets in Italy.

In addition, Iran's economy is also constantly committed to the transition to a non-oil economy, and has made a certain breakthrough. According to the customs released a report last week said that as of May 20, a month, Iran's oil exports and 80% growth compared to the same month last year, a total of exported 8.302 million tons of goods, such as, Iran's exports to China rose 86% to $974 million, and become Iran's largest export destination during this period, the foreign media said, Encouraging trade with its neighbors has been a key part of Iran's efforts to diversify its revenues. For example, many Iranian companies are actively seeking joint ventures or partnerships to fill gaps in their technology, infrastructure and business management.

The latest regional economic report released by IIF said that thanks to Iran's continuous improvement of business environment and development of economic structural transformation, it will achieve the fastest regional growth in the Middle East to 4.4% in 2021. If the US lifts or relaxes restrictions, it will even achieve a strong recovery of more than 6%. At the same time, Iran's economy, long subject to U.S. dollar sanctions and restrictions, has pioneered various ways to de-dollarize and achieved several breakthroughs.

For example, Iranian media recently reported that four Iranian banks are negotiating with nine countries -- Germany, France, the United Kingdom, Russia, Switzerland, Austria and South Africa -- on the use of cryptocurrency in trade settlement and financial transactions. So far, those countries have responded to Iran's currency move. A week ago, Russian authorities were quoted by Iranian media PressTV as saying that Russia was ready to leave Swift and pair up with systems including Iran's electronic financial messaging platform Sepam, China's CIPS and Europe's Sepa to avoid Swift.

Here, not only in the field of foreign exchange, in addition to Iran is officially in yuan instead of dollars, and the renminbi as one of the country's main foreign exchange currency, then, in a few weeks ago, Iran has passed legislation introduced state transition version of a new currency, will be the country's national currency conversion for soil, reports show that the soil will anchor the RMB exchange rate. It also means that China's Cross-border Interbank Payment System (CIPS), as an international payment system, can provide clearing and settlement services for international participants involved in cross-border payments and renminbi transactions.

In fact, the Iranian economy had been preparing to export more oil without the dollar. For months, Iranian crude has been stored in bonded warehouses in the Asian market, including the National Iranian Oil Company, which stores more than 20 million barrels in bonded warehouses in Dalian to decide whether to sell to Chinese or other foreign customers.

The latest news shows that in the past 14 months, Iran has shipped about 18 million tons of oil to the Chinese market, and most of the transactions have been conducted in RMB, which shows that the RMB has played a role as a currency of trade in Iran's oil trade.

Iranian media quoted experts as saying the move could prove successful and is part of a broader effort to move the economy away from oil revenues. As Mark Zuckerberg, the former governor of the Bank of England, pointed out. Carney said several weeks ago that the yuan would play a role in global oil trading, following a Japanese media analysis earlier in the day that said Asia should trade oil in yuan and yen.

At the same time, along with Iran and China's market economic and trade, and expand, Iran's Ministry of Transport in the news a week ago, said Iran has begun negotiations with Chinese contractors, seeking to attract a lot of money, to complete a connects the capital and the Caspian sea region of large road projects, the agency said that in the past few decades, Iran has spent billions of dollars on big infrastructure projects. Analysts say the Iranian economy may feel the value of the global "infrastructure mania". Similarly, a new breakthrough came when Iran's economy broke free of the dollar in a variety of ways.

According to the media reported a week ago, at present, the Swiss deals with Iran, it shows that Iran to cooperate with Swiss enterprises have to bypass the dollar, and the European central bank, said the support scheme of digital currency is expected to avoid SWIFT progress within months, at the same time Iran's central bank has also established a block chain monetary research, development with the support of local currency country encryption currency.

Following the announcement, IRSA said its funds have now replaced the banking system and managed to clear barriers facing Iran's engineering and technical services sector by issuing guarantees that could facilitate the use of sovereign digital currencies for commodities, including oil.
