虎口脱险

A |     Beijing has been branded the “biggest long-term threat to economic security” by the head of the FBI and the leader of Britain’s domestic intelligence agency.,FBI chief, Christopher Wray, in a rare joint appearance with Ken McCallum, the head of MI5, warned business leaders that the Chinese government was purportedly “set on stealing your technology, whatever it is that makes your industry tick, and using it to undercut your business and dominate your market”.,In a speech at MI5’s London headquarters, Wray and McCallum reaffirmed previously voiced concerns about economic espionage and hacking operations ostensibly being carried out covertly by Beijing.,“We consistently see that it’s the Chinese government that poses the biggest long-term threat to our economic and national security, and by ‘our’, I mean both of our nations, along with our allies in Europe and elsewhere,” Wray said.,Today in London, #FBI Director Christopher Wray and #MI5 Director General Ken McCallum addressed the threat posed by the Chinese Communist Party and the Chinese government, and why partnerships are crucial to combating it.

Aware of the growing “threats”, he added that the agency planned to consistently tackle the “attempts at inference” which pervade “so many aspects of our national life”.,The British intelligence officer who has been serving as the Director General of MI5 since 2020 hailed the fact that this was the first time the heads of the FBI and MI5 had shared a public platform.,“We’re doing so to send the clearest signal we can on a massive shared challenge: China,” McCallum said. He went on to denounce Beijing’s purported “covert pressure across the globe,” which amounted to “the most game-changing challenge we face.”,China Poses ‘Unprecedented’ Espionage, Cyber Security Threats to US, FBI Director Claims 25 April, 04:18 GMT,In response, a spokesman for the Chinese embassy in Washington, Liu Pengyu, slammed the unsubstantiated allegations spearheaded by the western leaders.,China, “firmly opposes and combats all forms of cyber-attacks,” he underscored in an emailed statement to the Associated Press.,“We will never encourage, support or condone cyber-attacks,” the statement added.,FBI Director Christopher Wray had brought up the alleged proliferation of cybersecurity attacks linked to China earlier in the year, as Federal Bureau of Investigation asserted that intelligence officials were facing cybersecurity and espionage threats from Beijing that were “unprecedented in history.,“The biggest threat we face as a country from a counterintelligence perspective is from the People’s Republic of China, and especially the Chinese Communist Party,” Wray stated in an interview at FBI headquarters on April 21, cited by a “60 Minutes” broadcast.,Wray yet again accused China of targeting American innovation, trade secrets, and intellectual property “on a scale that’s unprecedented in history.”,US Must Immediately Stop Cyberattacks Against China - Chinese Foreign Ministry14 March, 11:35 GMT,China has been consistently dismissing such allegations, calling on Washington, in turn, to adopt a more responsible position on cyberspace and stop cyberattacks against China.,"China urges the US government to take a more responsible position on cyberspace and stop malicious network activity immediately," Chinese Foreign Ministry spokesman Zhao Lijian said earlier this year, while slamming the US a "hacker empire."。      广西崇左8月23日电(涂丽莎 陈沿佑)秋日时节,广西崇左市扶绥县渠黎镇甜蜜之光现代甘蔗产业园满目青绿。桂糖44号、云蔗081609、桂糖76号、中糖3号、中辐1号等甘蔗品种长势喜人,大多数蔗株高度超3米。园区采用的多品种轮作、分区种植方式,保障了这片土地长期稳产与生态韧性。8月22日,广西崇左市扶绥县渠黎镇甜蜜之光现代甘蔗产业园。(无人机照片)周圆曦 摄  跟甘蔗打交道已有八年的杨学,从给种植户做技术指导,到创办农业科技公司。这些年,他见证甘蔗种植从靠老经验慢慢变成“科技种田”,心里装着一本清晰的对比账。在他看来,用上甘蔗脱毒种苗及其配套栽培技术,宿根年限能从3年延长到5年左右,出苗率可达95%。“崇左以前种甘蔗一亩大概收4吨,如今搭配新品种、新农艺、新种植模式,亩产提升到了4.8吨。
