Information from running the 2035 plan (from 2022) through Google Translate and comparing to what exists on OSM:

G0111 extends south to Binzhou (OSM and zh.wikipedia say the south end is G18)
G0112 complete, from Changchun to Liaoyuan per, but OSM shows only S routes
G0121 complete, with the gap filled and the extension to Qinhuangdao built
G0122 not yet
G0211 complete, from G0111 to where it becomes G2002 outside Shijiazhuang
G0212 not yet (currently S40)
G3 extends south to Suping (obviously doesn't reach Taipei as planned); realigned at Nanping
G0311 exists since 2022 per from G3/G2001 at Jinan to G0321 at Liaocheng
G0321 partly complete, from G3 south of Dezhou to S42 east of Qimen and G56 at Wuyuan ( claims it's open south from Tuochuan) to G6021 at Xingangshan ( claims it continues south to G60 on what OSM has as S19)
G0322 not yet (currently S3901, S3501 where built?)
G0323 partly complete, from G1511 at Jining (OSM shows it continuing north to G35, but the list says Jining and says that part is S33) to G3 near Xuzhou, Guzhen to G36 at Bengbu ( claims it continues south to S95, but the interchange with G36 is under construction?)
G0411 complete, from G4 at Anyang to G2212 at Changzhi (OSM shows it's S22 east of Linzhou, but says it "will become" G0411 in 2022)
G0412 not yet
G0413 not yet
G0421 complete, from G1516 at Xuchang to Guangzhou (partly mapped as G4W2, its old number)
G0422 complete, from Wuhan to S30 east of Shenzhen (OSM shows a large portion as S11, but appears to show it all as G0422)
G0423 complete, from G4 northwest of Lechang to G45/G94 north of Guangzhou (mapped as G4W3, its old number)
G0424 partly complete, from G30 east of Zhengzhou to G40 at Loushan; claims what OSM shows as S3601 south of Beijing is G0424; claims the portion south of G40 to Wuhan opened in 2023
G5 has been realigned between Shijiazhuang and Taiyuan using what we have as G5N and G2001. Former G5 is now G2002 and G20.
The G0501 and G0511 we have are not in the list or; the latter shows them as S2202 and S2211, respectively.
G0511 complete, from G5 north of Deyang to south of Dujiangyan
G0512 partly complete, from G5 south of Chengdu to G93 at Leshan
G0513 not yet
G6 partly compete, with the gap filled and an extension west to Golmud, plus Nagqu to west of Lhasa
G0611 partly complete, from G30 at Zhangye to south of Minle and Ebao/Ebuzhen (per OSM; shows the end near Menyuan) to north of Tongren
G0612 partly complete, from G6 at Xining Airport to G6 west of Xining, northwest of Caka to G3011 near Xiaochaidan? (OSM shows this as S2013 and S20, but says it's G0612), and Yetimbulak to Hotan ( says this is under construction east of Qakilik)
G0613 partly complete, with a tiny extension south from what we have, plus a piece from south of Shangri-La to G5611 west of Lijiang
G0615 partly complete, from south of Delhi to Ngawa
G0616 not yet
G7 partly complete; the gap in BJ still exists (but appears to be longer, with both OSM and not including S323 to S216 in G7); the gap between CHN-HE G7 and CHN-NM G7 has been filled; G7 now leaves what we have some distance east of Hami, with its own route to end at G30 northwest of Urumqi
G0711 partly complete, from Lopnur to Qakilik/Ruoqiang
G0712 not yet
G11 as we have it, except it bypasses Jiamusi to the west (OSM shows it complete but says it's under construction)
G1111 partly complete as we have it
G1112 complete, from Ji'an to G45 near Shuangliao (looks like the part we have is badly traced)
G1113 partly complete as we have it, except according to OSM and it does not exist south of G11_N
G1115 complete, from G11 near Jixi to G1012 (or G1011?) near Jiansanjiang (OSM shows S11 but claims it's now G1115)
G1116 not yet (looks like it's currently S12)
G1117 not yet (but isn't Suihua-Beian G1211?)
G1118 partly? complete, from G11 near Fusong to near Changbai Mountain (OSM shows S1 but claims it's now G1118)
G1119 not yet
G1131 partly complete, from Wangqing to G12 near Yanji

G1515 complete, from G15 north of Yancheng to G2/G40 near Jingjiang
G1516 partly complete, from southeast of Yancheng to G2/G2511 near Huai'an, and from S49 near Sihong to G36/G55 near Luoyang
G1517 complete, from southeast of Putian to G0422 near Yanling
G1518 partly complete, from Jinhu to G25 and G36 near Mingguang to G36 near Mohekou (OSM shows all as S routes but shows G1518)
G1519 partly complete, from G15 near Nantong to Rudong
G1521 complete, from G1522 near Changshu to G15/G92
G1522 complete (complete renumbering of our G15W)
G1523 complete, from Ningbo to G94/G9411 near Dongguan (including almost all of what we have as G15W3 and all of G1503) (OSM shows parts as S35 and S30, but says it's all G1523)
G1531 not yet
G1532 partly complete, from G72 west of Hushan to G25 near Meizhou (partly S10 on OSM, but says it's all G1532)
G1533 not yet
G1534 not yet
G1535 partly complete, from G15 west of Raoping to G1532 near Dama (may still be S11? OSM is contradictory and says S11) and G25 near Meizhou to G35 near Pingyuan

G2515 not yet
G2516 complete, from G18 near Kenli to G20 at Fenyang

G2519 complete, from G25 near Kangping to Shenyang (OSM shows S2 but says G2519)
G2531 not yet
G35 has been realigned between Qianshan and Dongzhi; the old alignment where not overlapped is S27
G3511 partly complete, from G1511 near Heze to Ronghe and G5 near Heyang to G85 near Fengxiang (doesn't look like the Linyi Yellow River Bridge is open yet to fill the gap)
G3512 not yet
G45 complete; it fills the gap at Beijing by using the east half of G4501. It seems that the former spurs are now S11 and G106 (not an expressway). The gap between Longnan and Conghua has been filled.
G4512 complete, from G45/G1112 near Shuangliao to one interchange past what we have at Nenjiang
G4513 partly complete, from G45 near Naiman Banner to Kouhezi and G25 near Fuxin to G15 east of Yingkou
G4515 partly complete, from G45 to G16 near Chifeng
G55 partly complete, as we have it? ( appears to show it complete from the eventual north end at Erenhot) (there seems to be a gap in southern Taiyuan; southbound traffic can't reach the supposed gap filler)
G5511 partly complete, from west of Ulanhot (not as far south as we have it) to G10 near Arun/Arong Banner (and maybe small pieces on either side of a G16 overlap from west of Heighten-Banner to east of Xinchengzi?)
G5515 partly complete, from G5513 near Zhangjiajie to Daguquan and south of Xianfeng to G42 southeast of Nanchong
G5516 complete, from G55 south of Sunite Right Banner to G95 near Guyuan (but the list says it goes to Zhangjiakou)

G5518 not yet (part seems to be S87)
G59 partly complete, from Hohhot to G20 at Luliang (filling one gap), G22 east of Ji ( says it now makes it north to near Jiaokou) to Wufeng ( seems to show more?), and G60 near Dongkou to Teishangang (OSM shows the north end of this at G78 south of Yangshuo, with north of there being overlaps or S91 and S2201; shows it continues north of G60 - but also shows Wugang to Xinning as G7221?)
G5911 not yet
G5912 not yet
G65 complete, from G6/G7 near Baotou to G15 near Maoming, filling the gap between CHN-HN G65 and CHN-GX G65 and extending it south; G65 replaced what we have as G65W
G6511 partly complete, from east of Zichang to G6521 near Qingjian (S14 on OSM but G6511 on
G6512 partly complete, from G65 near Xiushan to G60 near Linchong and north of Tianzhu to G76 near Luoxiang (all S routes on OSM, but says it's G6512)

G6521 complete, from G1812 north of Yulin to G40 near Lantian
G6522 replaced G65 where G65W existed

G6911 partly complete, from G4213 at Pingli to east of Huaping, Wuxi to G42 east of Fengjie, Changliang to G5515 near Laifeng
G75 partly complete, from Lanzhou to Dacaotan (Dacaotan to Meichuan may have just opened with the Muzhailing Tunnel?) and Meichuan to G98 near Haikou (except crossing near south end); realigned east of Guiyang; needs to be extended south at Xuwen with a short piece at Haikou
G7512 partly complete, from east of Gulin to Chengdu
G7521 partly complete, from Chongqing to G75 near Anwen and Banqiao to G69/G75/G6002 near Guiyang
G7522 not yet ( appears to be saying that S61 from G78 near Bama to Nanning is not yet G7522)
G85 partly complete, from southeast of Yinchuan to north of Huianbao (renumber from CHN-NX G69), east of Pingliang to Chengjiang (filling several gaps and extending; the east end of CHN-CQ G85 gets deleted, as does the south end of CHN-YN G85)

G8512 partly complete, from G8511 east of Jinghong to Menghai
G8513 partly complete, from G22/G70/G85 east of Pingliang to north of Linjiang, east of Wen to Shijiba, Baima to south of Pingwu, and west of Jiangyou to G5/G93 north of Mianyang
G8515 complete, from G42 at Guang'an to Luzhou ( seems to say that a more direct route is planned rather than all the overlaps OSM shows)
G8516 partly complete, from G85 north of Bazhong to S59 east of Chengdu
G8517 is all shown as S routes on OSM, but seems to say that it's mostly complete south of Yibin, except from south of Junlian to Zhenxiong?
G10 partly complete, only as we have it per OSM ( shows it extending to both borders, which doesn't make sense); also shows it overlapping G1001 south and west of Harbin (no idea if this is correct)
G1011 doesn't exist north of "G010_S" per both and OSM
G1012 as we have it per OSM; may show it extending west to G1011

G1016 not yet
G1017 not yet

G1815 complete, from G18 north of Weifang to G1511 near Rizhao
G1816 partly complete, from Shizuishan to S1 south of Zhongchuan (CHN-GS G1816 is no longer part of it; I'm not sure if OSM is correct to show old G18 east of Wuhai as G1816) and G75 north of Lintao (but the log shows Yongjing on the route!) to south of Hezuo
G1818 complete, from G18/G25 north of Binzhou to G3 near Dezhou (S12 on OSM but G1818 on

@neroute2: Are you simply reporting those Asian changes or are you going for taking over maintenance (temporarily) to rework the routes and systems?

Some sources which might help:
- SSC: News about Chinese roads (mainly reported from a Chinese living in US
- SSC: Summary of freeway-like road openings (often featuring OSM coords; you might want to search for "China" in this thread)
- wegenwiki: List of expressways in China (I think it's quite up-to-date)
- wegenwiki: Recent openings (similar to the SSC thread but tightly arranged)

btw: Topics merged.

Probably just reporting, since I'd rather someone with more familiarity do the actual changes.

If memory serves, @si404 told me not to update China for the time being. So, you might want to spend your time for other topics. I recommend agreeing in advance which systems you should review. I mean, I also started reviewing a lot of Asian, African and South American systems a year ago........

Did I say that? Or did I say that I've not updated China for a long time and it's well off ready for a review. I'm not going to stop anyone updating China, but there's a mountain to climb there as it's almost entirely the drafts I made 7 or 8 years ago!

I think have a template for China Gxxxx that's in a Draft PR here, I'm not sure how to correct test any changes needed in the PHP files though. But I think we can start with just plain replace ***NUMBER*** with the number (G1234)?
