【白宫官员：取消对加拿大征收50%的钢铁、铝关税】金十数据3月12日讯，美国白宫贸易顾问纳瓦罗当地时间周二下午表示，特朗普总统周三将不会把加拿大钢铁和铝进口关税提高到50%。六个小时前，特朗普宣布计划将加拿大金属25%的进口关税提高一倍，以回应加拿大安大略省对美出口电力征收25%附加费（在特朗普发出威胁后已取消）的决定，而安大略省的这一举动本身就是对特朗普对加拿大进口商品征收25%关税的报复。纳瓦罗还表示，对所有进口的钢铁和铝的25%关税将于12日午夜开始实施，且不会有豁免

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
Telegram is a cloud-based instant messaging service that has been making rounds as a popular option for those who wish to keep their messages secure. Telegram boasts a collection of different features, but it’s best known for its ability to secure messages and media by encrypting them during transit; this prevents third-parties from snooping on messages easily. Let’s take a look at what Telegram can do and why you might want to use it.
