该篇文章是关于这次美国带头推动联合国安理会加强对北韩的制裁，
想询问我这样翻译跟理解是否有误？

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.
试译：
美国官员尚未透露于安理会讨论有关制裁北韩的具体细节，但部分报导指出，中国对于新
制裁的各种草案内容没有任何回应。因为知道中国可能接受的底线在哪，美国才能更有效
地寻求各项单边、双边和多边的措施（或是称为二次制裁），但现在完全不明白中国
（和俄罗斯）愿意接受什么样的制裁。
