South and North Korea will march under a unity flag at next month's Winter Olympics in Pyeongchang under a deal achieved at the new round of talks at the Panmunjom truce village, the first such discussions in two years.  The two countries will also field a unified Women's Hockey team.  If the deal sticks, North Korea will send a big delegation - 230 cheerleaders, 140 orchestral musicians, and 30 taekwondo athletes for a martial arts demonstration - across the land border just before the Winter Games start on 9 February.

Japan is advising caution over North Korea's "charm offensive", reminding the world it was only a few weeks ago that Pyongyang was sending missiles over Japan in "tests" of its burgeoning nuclear weapons program.  "I am aware that some people argue that because North Korea is engaging in inter-Korean dialogue, we should reward them by lifting up sanctions or by providing some sort of assistance," said Taro Kono at a regional conference in Vancouver, British Columbia, "Frankly I think this view is just too naive.  I believe that North Korea wants to buy some time to continue their nuclear missile program."  The conference ended with 20 nations - not including China or Russia - signing a statement saying they would consider imposing sanctions on Pyongyang that are tougher than those specified in recent UN Security Council resolutions.

It's a very bad week for Bitcoin and other cryptocurrencies, with big sell-offs pushing the value way south of US$11,000 - which represent major losses for anyone who bought in at its peak of nearly US$20,000 back in December.  Number two Ethereum shed more than 25 percent of its value, while third-place Ripple dropped by more than 40 percent.  The crypto market is terrified of South Korea considering banning the trade in non-existent money over fears it is creating a gambling crisis.

Australia is accusing Canada of protectionism in its wine market.  The formal objection filed with the World Trade Organization says Canada has put in unfair regulations on foreign-produced wine, such as price mark-ups and requiring it to be sold only on special cash registers.  Aussie Trade Minister Steve Ciobo told the ABC, "In this case we've got a number of provinces in Canada that are putting in place pro-protectionist policies."  Mr. Ciobo also says Canadian rules had the potential to threaten jobs in Australia.

The United Nations World Health Organization (WHO) is warning anyone planning to visit Sao Paulo, Brazil to get a Yellow Fever Vaccine.  An outbreak in rural and forested areas has sickened 35 people since July, 20 fatally.  Sao Paulo state has seen the most infections.  Brazilian officials say people keeping to cities would be a less risk of the mosquito-borne illness.  Millions of international visitors are heading that way in the coming weeks, because Carnival is early this year - beginning on 9 February and running through the crazy weekend until the stroke of midnight on 14 February. 

Actor Jessica Falkholt has died from injuries she suffered in the Boxing Day horror crash that killed her family.  She had remained in coma since then, and doctors took her off of life support last week.  Ms. Falkholt featured in the popular TV show "Home and Away" and will appear in the US film "Harmony", which is set for release this year.

Serbian police arrested three Australians at a hotel in Belgrade, suspecting them of being part of an international drug-smuggling group linked to 1,280 kilos of cocaine worth a half-billion dollars that was seized on a Chinese boat docked in Sydney last year.
