China has begun puttingnew limits on the overseas sales of itsmost powerful supercomputers and drones. The move to limit some of the more advanced Chinese technologiesechoes U.S. restrictions on similartechnology exports.

Chinese companies seeking to export certain advanced supercomputers or drones will need to apply for export licenses, according to a 31 Julyannouncement byChina’s Ministry of Commerce and the General Administration of Customs. For supercomputers, that means anything more powerful than 8 teraflops (8 trillion floating-point operations per second), The Wall Street Journalreports. China currently has the world’s most powerful supercomputer, called Tianhe-2, at 33 petaflops (33 quadrillionfloating-point operations per second.)

The new Chinese rules likely represent an effort to play up China’s technology strengths, saidAndrei Chang, the Hong Kong-based editor of Kanwa Defense, an online publication about military affairs, in aWall Street Journal interview. But they may also represent a reaction to the U.S. government blacklisting several Chinese supercomputing centers associated with Tianhe-2 because of concerns about their involvement in nuclear weapons development.

Both China and the U.S. are leaders in building ever-faster supercomputers. But the U.S. currently lags behind China and Japan in terms of plans to buildthe first exascale supercomputers. The two Asian nations hope to get there by 2020. On 29 July, President Obama signed an executive order focused on high-performance computing that included the goal of speeding up delivery of the first U.S. exascale supercomputer, which experts don’t expect until 2023.

The new Chinese export license restrictions also cover homegrown drones that can fly for more than an hour, along with drones that can stabilize themselves in the midst ofstrong winds and fly for more than half an hour.That probably won’t affect the business oftheChinese company DJI, which produces the popular Phantom line of commercial drones andcurrently ranks as the world’s largest commercial drone manufacturer. But it could potentially limit future exports as off-the-shelf drones become more powerful.

中国已经开始把对其海外销售的新限制；最强大的超级计算机和无人机。此举限制一些更先进的中国技术；呼应美国限制类似；技术出口。

中国企业寻求出口某些先进的超级计算机或机器人将需要申请出口许可证，根据七月31 ；中国的公告；&rsquo；商务部和海关总署。超级计算机，这意味着超过8万亿次浮点运算更强大的东西（8兆次浮点运算每秒），华尔街日报报道。中国目前拥有世界上最强大的超级计算机，；叫天河2号，在33千万亿次（33万亿；浮点运算每秒。）

中国新规则可能代表了一种努力发挥中国&rsquo；的技术优势，说；安德列昌，基于香港汉和防务主编，军事在线出版物，在；华尔街日报采访。但他们也可能代表了美国政府的黑名单几个中国超级计算机中心与天河2号因为他们发展核武器的担忧中参与反应。

中国和美国的领导人在建设更快的超级计算机。但美国目前落后于中国和日本方面计划建立；第一亿亿级超级计算机。这两家亚洲国家希望在那里得到2020。29七月，奥巴马总统签署了一项行政命令，专注于高性能计算，包括加快美国第一亿亿级超级计算机交付的目标，专家不；没想到直到2023。

中国新的出口许可证限制还包括国产飞机能飞一个多小时，随着无人机能稳定自己在中间；大风飞了半个多小时，；这可能会影响；；企业；中国企业DJI，产生商业无人机的流行的幻影线；目前是世界上最大的商业飞机制造商。但它可能会限制未来的出口，因为现成的无人驾驶飞机变得更加强大。
