This article analyzes the Sino-US Summit in Osaka in 2019 and its influence on trade negotiations between China and the US in the near future. By a look at the reports from China’s side and the US’ side, the article figures out what has been agreed and what are the most controversial issues on table. Having an observation of the new development after the Summit, the article tries to analyze the direction and ways forwards for the Sino-US trade talks, and make predictions based on a certain of factors including challenges faced by the US, the need of China as well as the attitude of the world. It is easy to figure out that agricultural products and the supply of equipment relating to Huawei were the key points at issue in the Sino-US Summit as well as in the future. The exchange and compromises are necessary between China and the US regardless of whether they are happy to admit it or not.

In recent years, the Chinese government has been investing an enormous amount of money in infrastructure development across many of the island states in the area of the South Pacific. This essay will review such investments in Papua New Guinea, Fiji, Timor, Samoa, and Vanuatu and further analyze the underlying rationale. China seems to be interested in developing tourism in these islands, as well as building a close relationship with them in a geopolitical viewpoint. These cover the areas of agriculture, fishing, infrastructure, roads, bridges, ports, airports, highways, agricultural technologies, hydropower, stations, and sewage pipelines. Chinese overseas investments is more likely to be accelerated in this region.

Hypsizygus marmoreus (Peck) H.E. Bigelow is a typical white-rot fungus and is widely cultivated in China and Japan. In this study, the genome of a monokaryon strain HM26-F1 was sequenced using Illumina and Pacbio platforms. The genome sequences of 32,238,363 bp with 49.40% G+C content were obtained and 14,443 gene models coding for proteins were determined. The divergence time was 144 million years ago (MYA) and diverged from other fungi belonging to Agaricales around the late of Jurassic Period. 363 carbohydrate-active enzymes (CAZymes) genes were detected in this genome. And there were higher number of class II peroxidases (11) and multicopper oxidases (22) for degrading lignin. In addition, 418 genes were enriched involving in purine metabolism for IMP and GMP synthesis. And, there were 7 secondary metabolite clusters in the genome, including 3 terpene, 2 polyketide biosynthase, 1 nonribosomal peptide synthetase and 1 siderophore. Combining Hiseq 2500 and Pacbio platforms resulted in a more complete and less fragmented genome. H. marmoreus had high abilities to degrade lignocellulose. IMP and GMP may be the basis of the crab flavor. Information obtained from this study enhances our knowledge about degradation mechanisms of lignocellulose and secondary metabolism.

During the deregulation weave of natural monopoly industry in the word, reform of natural gas industry among those shows difference and complex. This paper aims at developing theoretical frame of industry organization model of natural gas, and it is illustrated by applying it to five countries. Firstly, based on three coordinating system theory nine organization models are identified, and described in more detail using additional structural features. In the following, developed theoretical frame is illustrated by applying it to four countries.
