Yes, certainly!

Site: Ustyurt Plateau
Countries: Kazakhstan, Turkmenistan, Uzbekistan
TWHS: no
Description: The Cold Winter Deserts of Central Asia, where several protected areas in Kazakhstan, Turkmenistan and Uzbekistan could qualify as components for a possible World Heritage listing, are an example of this potential (of new WHS). No such cold winter deserts feature on the World Heritage list to date. These unique landscapes harbour emblematic species for this region, including wild herds of the vulnerable goitered gazelle, the Asiatic wild ass and the urial. They also serve as an important breeding and migratory areas for bird species such as the eastern imperial eagle, the houbara bustard or the saker falcon. These areas are currently threatened by overexploitation and large-scale infrastructure development. A possible World Heritage status would help strengthen their conservation.

Re: Papua
After some research I think Kikori River Basin, covering 6% of PNG, is the most "representative" TWHS from the Papuan tentative list.
"There are few landscapes in Melanesia as dramatic with features including the extinct volcano of Mt Bosavi, cockpit and needle karst of the extensive Darai limestone, remarkable Hegigio Gorge and the spectacular Wassi and Wawoi waterfalls. The Kikori basin / Great Papuan Plateau contains one of the largest remaining tracts of undisturbed forest in the Southern Hemisphere. The catchment spans across nearly all forest types found in PNG, from alpine and montane forests in the north, to increasingly rare intact lowland forests in the south, to the largest block of mangrove forest in the Pacific." (TWHS description)

I don't much about these regions and haven't done researches yet. I will try to look for highly valuable sites. Looking back at your proposal I would actually like to support this one.

I wouldn't have a problem putting all three sites forward now. They all seem great to me but hard to tell apart. I understand they all contain numerous ecosystems representative of New Guinea and diverse flora and fauna including endemic species. However, how they differentiate from each other is harder to figure out.

This is something I can certainly live with. So my support to all three as well.
For Els, these are Trans-Fly, Owen Stanley Ranges and Kikori.

Transnational proposal between China and North Korea.

Full Name of Site: Sacred Mountain Landscape: Changbai Range and Mt Paektu
Country: China, North Korea
TWHS? Vertical Vegetation Landscape and Volcanic Landscape in Changbai Mountain added to China's tentative list in 2017. Mt Paektu Global Geopark (North Korea) applying for UNESCO Geopark status in 2020

Short description of site: The mountain has been worshiped by the surrounding peoples throughout history. Both the Koreans and Manchus consider it sacred, especially the Heaven Lake in its crater.

"the world's highest volcanic crater lake" - UNESCO Nomination Description

"The 946 eruption of Paektu Mountain in Korea and China, also known as the Millennium Eruption or Tianchi eruption, was one of the most powerful volcanic eruptions in recorded history and is classified as a VEI 7 event." - Wikipedia

Criteria: Mixed
Outstanding universal value / comparative analysis: Volcanoes of Kamchatka (Russia), Mount Kumgang (North Korea), Mount Fuji (Japan), Jeju Volcanic Island and Lava Tubes (South Korea)

I support this proposal. Specifically transnational cultural sites are missing outside Europe and here the transnational concept seems justified.

I would support this missing gap on the world heritage list.

The Asia and the Pacific region (defined by UNESCO) is incredibly large, so I broke the region down to see what we might be overlooking.

So I've been a bit busy this week, but there is a site that seems like an interesting one for Bangladesh.

Full Name of Site: Panam Nagar, Sanargaon -- Center of the Muslin Trade
Country: Bangladesh
TWHS? No
Short description of site: Sonargaon is a city with centuries of Muslim and Hindu rule, and was a former port and capital of Bengal between the thirteenth and fifteenth centuries. The city was also a historic trading center, central to the muslin trade in Bangladesh during the 17th and 18th century. The British East India Company arrived in the 19th century and helped develop the Panam Nagar section of the city, in order to purchase muslin and other textile goods. This neighborhood contains over 50 historic buildings built by Hindu merchants but later abandoned in the 20th century. This former textile trading center has been declared a protected heritage site by the Bangladeshi government.

Criteria: Cultural
Outstanding universal value / comparative analysis: Silk Roads: the Routes Network of Chang'an-Tianshan Corridor

Also, looking back at the list for some sights that have not been seconded yet, I'll second Baikonur Cosmodrome, the Coral Stone Mosques of the Maldives, the Cretaceous Dinosaur Fossil Sites in the Mongolian Gobi (which I already seconded, but if as proposed a site just be put forward as The Great Gobi Desert, encompassing all the Gobi desert nominations, I'd be in favor of that), Napier, Ustyurt Plateau, Colonial Hanoi, and Ban-Gioc Waterfall.

Pakistan should have 2 sites - Harappa, Central Karakoram NP
What to do about Indian sites which was earlier proposed & I amended

1) Ranakpur changed to Ranakpur & Dilwara Temples - I changed as both have similar Jain marble intrinsic carving Marvel architecture. Also, Dilwara was proposed in 2014 list.
2) Gol Gumbaz changed to Deccan monuments - To sync with TL

If anyone does not support my ammendments, then I will have to second with earlier proposal suggested in the forum

I voted for this proposal in my Top Missing for 2014 (#73) and I will do so again now. It never cracked the Top 50 missing or even the Top 50 Remaining Missing after several sites were inscribed.

This looks promising an intact urban ensemble of sites, I support this proposal. Does Solvigant or Els have any thoughts on any quintessential sites in Bangladesh to be considered for Top 50 Missing? Based on your reviews, you both seemed to have preference for these sites, no?

Puthia Temple Complex

Kantajew Temple

"Unfortunately I doubt that Mahansthangarh will ever make it on to the World Heritage List. Bangladesh has a couple of more interesting sites on offer, of which I especially liked Puthia and Kantanagar. These sadly don't figure on the current Tentative List of Bangladesh." - Els Review

"Kantaji Temple" together with "Sonargaon" and "Puthia" (in the form of the Govinda Temple - but the whole of this atmospheric village estate should be preserved)." Solivagant Review
