該篇文章是關於這次美國帶頭推動聯合國安理會加強對北韓的制裁，
想詢問我這樣翻譯跟理解是否有誤？

American officials have yet to disclose the specifics of what is under
discussion at the Security Council; some reports indicate that the Chinese
have not even reacted to various drafts of a new resolution. Because there
are clear limits to what China might be prepared to accept in a new Security
Council resolution, the United States is actively exploring various
unilateral, bilateral, and multilateral measures—also known as secondary
sanctions—that go well beyond the particulars that China (and Russia) will
entertain.
試譯：
美國官員尚未透露於安理會討論有關制裁北韓的具體細節，但部分報導指出，中國對於新
制裁的各種草案內容沒有任何回應。因為知道中國可能接受的底線在哪，美國才能更有效
地尋求各項單邊、雙邊和多邊的措施（或是稱為二次制裁），但現在完全不明白中國
（和俄羅斯）願意接受什麼樣的制裁。
