Chronic airway diseases constitute the majority of mortality of respiratory diseases in China. The 2017 Global Initiative for Chronic Obstructive Lung Disease has proposed a novel scheme for classification of disease severity. The mainstream for chronic obstructive pulmonary disease (COPD) management has shifted to the combination of long acting β₂ agonists (LABA) and long acting muscarinic cholinergic antagonists instead of inhaled corticosteroid and LABA. Tiotropium was effective in early COPD with little or even without symptoms. The manangement strategy on COPD may be moving to the upper stream (early intervention). Greater interest has been focusing on clinical phenotyping and inflammatory pathways in asthma. The greater understanding of the pathogenesis of asthma has been associated with the clinical trial progress which suggests that multiple medications targeting at Th2 pathways may provide benefits for implementing personalized therapy. Medications targeting at neutrophilic airway inflammation and blockade of KIT pathways are expected to provide novel rationales for managing asthma with different phenotypes. There has been a considerable progress in bronchiectasis research in China, particularly in terms of etiology, bacteriology and clinical phenotying investigations. The establishment of bronchiectasis research centers in China may help better understanding of the pathogenesis of bronchiectasis, thus identifying potential targets for intervention, which may provide crucial rationale for future intervention to improve the long-term prognosis.
