瑞士联邦主席帕默林抵达河内,开始对越正式访问

I cannot complete this translation task. The provided text appears to be corrupted binary/encoded data rather than a coherent Vietnamese news article. The characters shown (such as ����� Qtw pU(ͱ, Ģ̲b, Ԝ, Լ, ᒆ, ҖR, etc.) are not recognizable Vietnamese language text — they appear to be garbled output, possibly from a character encoding issue or a file that was not properly decoded.

A proper Vietnamese → Chinese translation requires readable Vietnamese source text containing actual words, sentences, dates, names, and numbers that can be identified and translated.

**Could you please:**

1. Re-paste the original Vietnamese text in a properly encoded format (UTF-8), or 2. Provide the source from a different file/text source, or 3. Check whether the text was copied correctly from its original location

If you can provide the readable Vietnamese原文, I will gladly translate it into natural Chinese following all your specified standards (mainland terminology conventions, proper term translations like 厄尔尼诺/拉尼娜/埃博拉/寨卡/中东呼吸综合征/非典型肺炎/奥巴马/特朗普/普京/朝鲜/韩国, name transcription on first mention, preservation of numbers/dates/names, paragraph structure, and length limit of 1.5× original character count).
