Yes, every small gesture or major initiative will matter. Passing a motion in the Canadian Parliament saying that the one country, two systems of Hong Kong should prevail and that violations of it should be condemned; passing a resolution in the UN Human Rights Council, on Hong Kong; having coordinated efforts with other countries to do similar things in their parliaments, including passing acts in the different governments and executive orders that the one country, two systems in Hong Kong should be upheld—all of these should be recorded so that there's a reference.
When it happened in Tibet in the 1950s, many countries felt the same. They did not support us at the United Nations. Of course, we passed three resolutions; thereafter, they did not. Canadians and all of the governments essentially did not put anything on the record. The more noise you can make, the more resolutions you can pass, the more hearings you can hold, the more opinion pieces you publish in newspapers...will be very helpful.
Eventually, democracy is inevitable. We must push China to embrace democracy, and human rights should be guaranteed. Eventually it will all happen, but for that to happen, coordinated efforts and bilateral efforts to press the Chinese government are very, very important.
