2010年,海地发生了一场毁灭性的大地震。 七级地震把首都太子港夷为平地。 超过二十万人死亡,一百五十万人无家可归。 全世界的同情心和捐款如潮水般涌来。 国际社会承诺的援助总额超过一百亿美元。 数百个国际援助组织涌入了这个加勒比海上的小国。 但十年之后,海地依然是西半球最贫穷的国家。 那些钱去哪了? 故事要从一袋大米说起。 地震后,美国政府紧急向海地运送了大量免费大米。 本意是救命。饥饿的人需要食物,这没有任何争议。 但紧急阶段过后,免费大米并没有停止。 它持续了好几年。 对海地的农民来说,这是一场慢动作的屠杀。 海地本国的大米种植业原本养活着数十万农民家庭。 他们的米虽然产量不高,但那是他们的生计。 现在,免费的美国大米铺满了市场。 谁会花钱买本地米,当免费的美国米堆在街边? 海地大米的价格崩盘了。 农民们卖不掉自己的粮食,纷纷放弃了土地。 他们涌入太子港的贫民窟,加入了那些等待援助的人群。 等待更多的免费大米。 不只是大米。 国际组织运来了大量免费的旧衣服。 海地原本有一个虽然小但还活着的服装产业。 免费旧衣一到,本地的裁缝铺和小服装厂全部关门了。 谁会花钱做衣服,当免费的T恤像垃圾一样堆在路边? 建筑业也一样。 地震后的重建工作几乎全部由外国承包商完成。 他们带来了自己的工程师、自己的设备、甚至自己的工人。 海地本地的泥瓦匠和木匠站在工地外面,看着外国人重建他们的国家。 那些一百亿美元的援助,大部分在抵达海地之前就已经被花掉了。 据估计,每一美元的国际援助中,只有不到一分钱真正到达了海地普通人的手中。 剩下的钱去了哪里? 外国咨询公司的高额顾问费。 国际组织工作人员的五星级酒店账单。 从美国本土采购物资的运输成本。 甚至连援助组织在海地租用的办公室,都把当地的房租推高了好几倍。 普通海地人反而更加租不起房子了。 前美国总统克林顿曾经担任海地地震恢复的联合国特使。 多年后他公开承认了这个系统的失败。 他说美国长期向海地倾销补贴大米的政策,摧毁了海地的农业自给能力。 他用了一个词:这是个错误。 2022年,距离地震已经过去了十二年。 海地的经济比地震前更糟糕。 政治陷入混乱,帮派控制了太子港的大片区域。 上百亿美元的援助,留下了一个比灾难之前更加破碎的国家。 🖊️这就是发展经济学中经典的"援助诅咒"。 帮助一个人最危险的方式,是替他做所有他本可以自己做的事。 你以为你在给他鱼,其实你是在杀死他手里那根鱼竿。 最残忍的善意,不是不帮忙,而是帮到让对方再也不需要自己站起来,也再也没有能力站起来。

今天,我收到一位朋友發來的照片,講的是敘利亞阿勒頗的屋頂被太陽能板蓋得密密麻麻,那些深藍色的面板幾乎全是中國的產能壓出來的。 戰後電網幾乎全毀,政府一天只供四五小時電,普通人裝不起柴油發電機,但中國把面板價格打到地板價,幾百瓦的板子一百多美金就能拿下,普通家庭都裝得起。 從伊德利卜到阿勒頗,西北部已經成了太陽能的海洋。醫院、水泵、難民營、甚至農田灌溉,全靠這些板子。當年躲砲彈的人,現在晚上至少能點燈。 後來,我請朋友再核實了一下,查對了來自敘利亞官方媒體的報導。 請大家繼續核實。

JUST IN🇨🇳🇵🇸❌🇮🇱🔥 Chinese military cargo planes arrives with humanitarian aid to the people of Palestine.
Readers added context they thought people might want to know
The planes in the video are C-17 Globemasters operated by the US, not China, which does not have this aircraft and has not conducted airdrops to Gaza. ukdefencejournal.org.uk/false-claims-o… factcheck.afp.com/doc.afp.com.47…

Rogoff now thinks the Yuan will be a reserve currency in 5 years, because 1. current US fiscal policy and trade wars are weakening the dollar's global anchor status. But we are entering a multipolar world, and the yuan becomes a primary reserve asset alongside the dollar and euro. 2. it it is becoming "unnatural" for Asia to remain so dollar-centric when China is the region's dominant trading partner. 3. He expects a "Nixon Shock" style transition where Asia moves into a yuan-bloc.

Nvidia CEO Jensen Huang breaks the myth: The US–China AI competition isn’t about one chip or one model, it’s a five-layer ecosystem. Energy, chips, infrastructure, models, applications. And on four of them, China is already ahead or catching up faster than sanctions can stop. When America bans, China builds. When export controls tighten, China accelerates. You don’t slow a rival by locking the gate, you only teach them how to build their own house.

在新疆建立新水系,全球这样大面积治理生态的国家只有中国这么一个。 这样治理10年,即便只有20%的土地变成良田,中国就会多出1.8亿亩耕地,按照中国人独立自主的精神,未来大豆也许都不依靠进口
