Bill S-219's statement that the present government of Vietnam is not legitimate can be interpreted as nothing other than foreign policy. If Canada's Foreign Affairs people had actually adopted it, it would have embarrassed Canada.
We don't know why it wasn' adopted. Perhaps it was because Harper's foreign affairs minister resigned just as the bill came up for debate. (Payton, 2015)[234]
Canada and Vietnam are still good friends.(Canada, 2018)[292] The Canadian ambassador in Vietnam describes the formal recognition of the Saigon regime in the bill as "a domestic issue".
In terms of anti-Vietnam policy, Harper moved cautiously without reference to the bill. He buried his anti-Vietnam initiatives inside other initiatives such as the memorial to victims of communism and the ambassador for religious freedom. These initiatives did not last past the end of the Harper government.
Under the Liberal government, Stephane Dion did make one small, slightly blundering effort to continue with an anti-Vietnam policy. (Dion, 2016)[206] This was something the Liberals had never done before and he did not last long as Minister of Foreign Affairs.
The bill, nevertheless, has the potential to affect Canada's Vietnam policy and turn it negative in the future.
One of the things Harper did in preparing for bill S-219 was appoint a former Saigon government official to the Senate.[7]
Senator Ngo spends a lot of time and government money on efforts to discredit the Vietnam government. (Ngo, n.d.)[192] The Senator is a one-man foreign policy. Although his efforts are funded with government money, they do not constitute official government policy.
If another Conservative government should be elected in Canada, it will undoubtedly respond to the Senator's efforts.
There is another way the bill affects Vietnam.
The bill very effectively endorses the various anti-Vietnam political factions that exist in Canada. It gives the license to conduct their activities from Canada, and they do.[11]
Canada indirectly supports them by enabling people who get into trouble in Vietnam to come to Canada as "refugees".[10] Quite a number were admitted while Harper was in power, and we are not sure that the practice has stopped. Senator Ngo also likes to bring such people to public attention. (Ngo, 2019).[472] It seems to be OK with Canada if people wish to violently overthrow the government in Vietnam -- just don't try it in Canada.
