Just for the two first one. I travel often in China, and USB regulation started 15~20 years ago in China, only apple that was not sold anymore in China at this time didn't follow the rule. The rest of the world follow it to not loose the Chinese market. At the same time they first move to low energy bulb light before EU, and few years after LED light, still far before EU too.The roaming for network work also in China, and in lot of other countries around the world. Only Japan (even still in OCDE/OTAN (2 names for about the same entity)) doesn't follow it for roaming.For Ambassy, At least a base, if we consider it as a united entity... I think that's the same inside united kingdom, united states of America, United states of Mexico or Federation of Russia (that is divided in several republics etc...)At the moment, the law of UE alow French or German companies too exploit workers of poorer Eastern countries, and you see so much trucks on road because unified railroads is against holy free market of private trucks. EU basicaly killed Chypre and Greece people, close schools, hospital and lot of basic services everywhere, in holy name of free market too.Europe is from root bad, The treaty that was rejected by referendums, but forced with Lisbon treaty, put the holy free market (neofeodal rule) above all other rules, and it's the constitution ! Law are only patchs of this master rules. Spain, and Portugal shown the way to not bend to these stupid rules. They developed a lot of renwable energy and don't accept that their citizen pay electricity at the price of the gaz energy unit. They made rules to have everyone access to public transportation too.
