How, and if, the Trump administration plans to regulate the export of semiconductors has remained unclear since Donald Trump took office last year. Now, we have an idea of what the administration is thinking. U.S. regulators have allegedly drafted rules that would require U.S. government approval to ship AI chips anywhere outside the U.S., according to Bloomberg, citing sources. This would give the U.S. significantly more control over companies like AMD and Nvidia. TechCrunch reached out to AMD, Nvidia, and the U.S. Department of Commerce for comment. In these drafted rules, companies and governments outside the U.S. would have to be granted approval by the U.S. Department of Commerce to purchase these chips. The review process would vary based on the size and scale of the potential purchase, Bloomberg reported. For example, a small order by a company outside the U.S. may warrant a basic review while a sizable order could require the company’s corresponding government to get involved. This could, of course, all change before a final announcement or ruling, but the proposal would represent significantly more government involvement than the AI Diffusion rule instituted under President Joe Biden. The Trump administration formally rescinded Biden’s diffusion regulation last May, less than a week before it was set to go into effect. While this is the first inkling of what broad export restrictions would look like, it isn’t fully surprising that the Trump administration is looking for more government involvement as opposed to less based on how it has handled Nvidia’s potential exports to China. The Trump administration has flip flopped multiple times on whether or not the company could send its advanced AI chips to the Chinese market before deciding to allow exports if the U.S. Department of Commerce was able to approve the customers.

Scott Barbour/Getty Images News Shell ( SHEL ) signed several agreements with Venezuela's government that span offshore natural gas and onshore oil and gas ​opportunities, Reuters reported Thursday. Shell ( SHEL ) also signed ​several technical and commercial agreements with Venezuelan engineering company ⁠VEPICA, as well as with KBR ( KBR ) and Baker Hughes ( BKR ), the report said. TV FANB, a Venezuelan state television channel, said in a post that the ⁠new ​agreements "reaffirm that Venezuela continues to ​be a safe and reliable destination for foreign investment." Shell's ​( SHEL ) long-running Dragon offshore gas project in Venezuela has suffered setbacks in recent years as U.S. policy toward Venezuela grew more hostile; in February, the company said oil and gas exploration licenses issued by the U.S. would allow it to move ​forward with the ​project.

Looking at the universe of stocks we cover at Dividend Channel , in trading on Monday, shares of 3M Co (Symbol: MMM) were yielding above the 2% mark based on its quarterly dividend (annualized to $2.92), with the stock changing hands as low as $143.91 on the day. Dividends are particularly important for investors to consider, because historically speaking dividends have provided a considerable share of the stock market's total return. To illustrate, suppose for example you purchased shares of the S&P 500 ETF (SPY) back on 12/31/1999 — you would have paid $146.88 per share. Fast forward to 12/31/2012 and each share was worth $142.41 on that date, a decrease of $4.67/share over all those years. But now consider that you collected a whopping $25.98 per share in dividends over the same period, for a positive total return of 23.36%. Even with dividends reinvested, that only amounts to an average annual total return of about 1.6%; so by comparison collecting a yield above 2% would appear considerably attractive if that yield is sustainable. 3M Co (Symbol: MMM) is an S&P 500 company, giving it special status as one of the large-cap companies making up the S&P 500 Index. In general, dividend amounts are not always predictable and tend to follow the ups and downs of profitability at each company. In the case of 3M Co, looking at the history chart for MMM below can help in judging whether the most recent dividend is likely to continue, and in turn whether it is a reasonable expectation to expect a 2% annual yield.

【有線新聞】美軍中央司令部聲稱炸毀30艘伊朗船艦，包括一艘無人機航母，總統特朗普指必須有份參與挑選伊朗最高領袖接班人，又指伊朗想跟美國達成協議，不過伊朗否認。 以色列再空襲伊朗首都德黑蘭等地，聲稱已發動2,500次攻擊，摧毀境內約八成防空系統，近乎完全控制伊朗領空。美軍中央司令部則擊中伊朗一艘無人機航母，累計炸毀逾30艘伊朗船艦。並出動B-52轟炸機等，在過去72小時攻擊境內200個目標，令伊朗的彈道導彈及無人機襲擊分別大減90%及83%，下階段會集中打擊伊朗生產導彈能力。戰爭部長海格塞斯稱，行動才剛開始，針對伊朗的火力將大幅提升，重申有足夠彈藥持續作戰。 總統特朗普接受外媒訪問稱，期望徹底剷除伊朗領導層，並交由好的領袖帶領國家，認為華府必須有份參與挑選新領導人，不可接受伊朗已故最高領袖哈梅內伊兒子穆傑塔巴接棒。他稱美國和以色列正聯手剷除伊朗軍力，進度超前，海軍和空軍不再存在，又指伊朗有意跟華府談判。「但她們態度強硬並想作戰，她們致電問『我們應如何達成協議？』我說有點太遲了，我們現在比她們更想戰鬥。」 不過伊朗外長阿拉格齊反駁稱沒有要求停火亦無意談判，已預備好應對美軍地面進攻伊朗，又說任何人不能介入伊朗推選最高領袖工作。革命衛隊則發射海巴爾—謝坎中程彈道導彈反擊，及出動無人機空襲以色列特拉維夫。
