Mar mhonaróir slabhra nasc cruach cruinn ar feadh 30 bliain, tá ár n-mhonarcha ag fanacht le agus ag freastal ar an tréimhse an-tábhachtach d'éabhlóid an tionscail slabhra na Síne ag freastal ar mhianadóireacht (mianach guail go háirithe), ardaithe trom, agus ceanglais iompair thionsclaíoch ar ard-neart bhabhta. slabhraí nasc cruach. Ní stopaimid de bheith ar an monaróir slabhra nasc cruinn tosaigh sa tSín (le soláthar bliantúil os cionn 10,000T), ach cloíimid le cruthú agus nuálaíocht gan stad.
