Thank you LT, you have my blessings ) But I slightly disagree with the suggestion for specifying the two eras "15th-18th century" and "18th-20th centuries" with "Cham vassals" and "Increasing trade". If you read the content carefully, the two eras are definitely not restricted to relations with Champa and trade. In the 20th century, the VN Communists played a significant role in building the MCP. I felt that adding contrasting aspects of Malayan/Malaysian-Vietnamese collaborations and contacts adds spice and flavour to the article. 

If you trace the article history, I had made an attempt to summarise the reference to "Tonkinese soldiers had captured a Malaccan tributary mission ...." to its current form. (You may wish to refer to the earlier version for reference: https://en.wikipedia.org/w/index.php?title=Malaysia%E2%80%93Vietnam_relations&oldid;=562411447) I definitely welcome any additional attempts to paraphrase further if possible, and the bulk of the quotation (very badly done for the prior revision) was quoted as part of the Bibliography. I am partly doing this to avert the possibility of any edit wars from previous editors, who may have strong feelings in the inclusion of particular paragraphs or points into the article body in the foreseeable future.
