Mar mhonaróir slabhraí nasc cruach bhabhta le 30 bliain, tá ár monarcha ag freastal ar an tréimhse ríthábhachtach d'éabhlóid thionscal déanta slabhraí na Síne agus ag freastal uirthi, ag freastal ar riachtanais mhianadóireachta (mianach guail go háirithe), ar ardú trom, agus ar riachtanais iompair thionsclaíoch maidir le slabhraí nasc cruach bhabhta ard-neart. Ní stadfaimid de bheith ar an monaróir slabhraí nasc bhabhta is mó sa tSín (le soláthar bliantúil os cionn 10,000T), ach cloímid le cruthú agus nuálaíocht gan stad.
